Compelled Speech, Constitutional Contamination, and the Fiction of “Administrative Only” Interviews

For nearly sixty years, constitutional law has drawn a clear boundary around the government’s power to compel speech from its own employees. That boundary is not ambiguous. It is not discretionary. And it is not dependent on how an agency labels an interview. Yet in practice—particularly within law-enforcement agencies—that boundary is repeatedly crossed under the guise of “administrative” questioning, producing a cycle of compelled speech, constitutional contamination, and belated litigation.

This analysis addresses a recurring and consequential question: can NYPD employees be compelled to answer questions during a department interview when they are suspected of criminal conduct, without violating the Fifth Amendment? The short answer is yes—but only under conditions the government routinely ignores. The longer answer exposes a structural failure that has less to do with legal uncertainty than with institutional convenience.

The governing framework begins with Garrity v. New Jersey (1966), where the Supreme Court held that the government may not force a public employee to choose between self-incrimination and job loss. Statements extracted under that threat are constitutionally coerced and inadmissible in criminal proceedings. Gardner v. Broderick and Uniformed Sanitation Men v. Commissioner refined the rule: a public employee may be compelled to answer questions about official duties—but only if those answers are immunized from criminal use. An employee cannot be terminated for invoking the Fifth Amendment when immunity has not been provided; conversely, once immunity attaches, refusal to answer job-related questions may itself constitute grounds for discipline.

Kastigar v. United States (1972) completed the framework by clarifying that “use and derivative-use immunity” is constitutionally sufficient to compel testimony. But Kastigar also imposed a heavy price on the government for choosing compulsion: in any subsequent criminal prosecution, the state bears the affirmative burden of proving that no evidence—direct or indirect—was derived from the compelled statements. That burden is not rhetorical. It is evidentiary, exacting, and often fatal to prosecutions that proceed after compelled interviews.

New York resolved the operational consequences of this doctrine more than four decades ago. In People v. Feerick, the Court of Appeals eliminated any lingering ambiguity about how Garrity operates at the state level. Feerick held that when a public employee is compelled, under threat of discipline, to answer questions related to official duties, immunity attaches by operation of law. It does not depend on formal incantations. It does not require a prosecutor’s blessing. And it cannot be retroactively denied by characterizing the interview as “administrative” rather than criminal.

For the individual employee, this means that once compulsion occurs, the constitutional risk no longer belongs to the officer—it belongs entirely to the government.

That holding matters because it exposes the central fiction that continues to animate internal investigations: the idea that agencies can compel answers first and sort out constitutional consequences later. They cannot. Once compulsion occurs, the constitutional die is cast. The employee’s statements—and anything derived from them—are immunized, whether or not investigators acknowledge that reality at the time.

Despite this settled law, compelled interviews in New York routinely proceed in ways that ignore Feerick’s command. Employees are ordered to answer questions while criminal investigations are active, foreseeable, or plainly imminent. Investigators disclaim criminal intent while coordinating—formally or informally—with prosecutorial offices. Employees are told interviews are “administrative only,” as though that label carries constitutional weight. It does not.

That failure is not merely episodic; it is reinforced by interrogation and false-statement policies that are facially compliant in form, yet routinely defeated in sequencing and practice—creating institutional incentives to obtain statements first and litigate immunity later.

The result is not lawful dual-track investigation. It is constitutional contamination.

This failure has predictable consequences. Prosecutors inherit cases burdened by compelled statements they did not wall off at the outset. Investigative leads become impossible to disentangle from immunized speech. Witnesses are identified, documents are pursued, and charging decisions are shaped by information the Constitution forbids the state from using. When challenged, the government is forced to meet Kastigar’s burden—often years later—by proving that its case was built entirely from independent sources. In complex law-enforcement investigations, that burden is frequently insurmountable.

What makes this pattern especially troubling is that it is unnecessary. The law does not prohibit discipline. It does not shield misconduct. It does not prevent criminal prosecution. It simply requires sequencing. If the government wants answers immediately, it must accept immunity. If it wants to preserve criminal exposure, it must refrain from compulsion. What it may not do is attempt to have both.

The persistence of compelled interviews without proper constitutional safeguards is therefore not a misunderstanding of doctrine. It is a governance failure. Agencies benefit from compelled cooperation in the short term while externalizing constitutional risk onto employees and courts. Prosecutors attempt post-hoc insulation rather than insisting on ex-ante compliance. Courts are left to adjudicate suppression and dismissal motions that should never have been necessary.

This analysis proceeds from a simple proposition: the Fifth Amendment is not a technicality, and Feerick is not optional. Compelled speech is a constitutional event, not an administrative convenience. Once the government crosses that line, it assumes obligations it cannot later disavow.

What follows traces the doctrine from Garrity through Feerick, explains how and why violations persist in practice, and sets out what lawful compelled interviewing would actually require if the Constitution were treated as a constraint rather than an obstacle.

I. The Constitutional Problem Framed

The Unconstitutional Choice

The constitutional problem addressed in this analysis begins with a choice that the Fifth Amendment expressly forbids the government from forcing: speak and risk criminal exposure, or remain silent and lose your job. For public employees—particularly police officers—this is not a hypothetical dilemma. It is a recurring feature of internal investigations, disciplinary interviews, and so-called “administrative” questioning conducted in the shadow of criminal law. For the individual officer or public employee, this dilemma is not abstract—it determines whether cooperation today becomes criminal exposure tomorrow.

The Fifth Amendment does not prohibit the government from asking questions. It prohibits the government from compelling answers under threat of punishment when those answers may be incriminating. Yet in modern law enforcement agencies, that prohibition is routinely tested—sometimes deliberately, sometimes casually—through investigative practices that blur the line between administrative oversight and criminal inquiry.

The dilemma is especially acute in policing because the same conduct frequently implicates both departmental rules and criminal statutes. Excessive force, false statements, unlawful searches, evidence tampering, misuse of authority, and corruption are not merely violations of internal policy. They are crimes. When an officer is questioned about such conduct, the risk of self-incrimination is neither speculative nor remote—it is immediate and foreseeable.

Unlike most public employees, police officers operate under a regulatory structure that virtually guarantees overlap between administrative discipline and criminal exposure. Internal Affairs Bureau investigations often track the same factual terrain as district attorney inquiries. Civilian oversight bodies examine conduct that may later be referred for prosecution. Inspectors General review incidents that already involve potential criminal liability. In this environment, the notion that an interview can be meaningfully labeled “administrative only” is more aspirational than real.

That overlap creates a constitutional fault line.

When a police officer is ordered to answer questions by a superior—explicitly or implicitly—under threat of discipline, suspension, or termination, the coercive force of the state is unmistakable. The officer is not speaking voluntarily in the ordinary sense. The choice is constrained by the power of the employer, backed by the weight of the badge, the pension, and the career. That is precisely the circumstance the Fifth Amendment was designed to address.

Yet internal investigations frequently proceed as though this constitutional reality does not exist. Officers are summoned to interviews described as “routine,” “fact-finding,” or “administrative.” The presence of counsel may be discouraged or limited. Criminal implications are downplayed. Formal warnings are omitted or delivered ambiguously. The expectation is clear: answer the questions now, and deal with consequences later.

This is not neutral fact-gathering. It is compelled speech.

The coercion need not be overt to be unconstitutional. An officer does not need to be explicitly told, “Answer or be fired,” for the threat to be real. In hierarchical institutions like police departments, authority is implicit. Orders carry consequences even when not spelled out. When an officer reasonably understands that refusal to answer will be treated as insubordination or lack of cooperation, the constitutional trigger has already been pulled.

The problem is compounded by the existence of parallel investigations. An officer may be questioned by Internal Affairs while a criminal investigation is ongoing, anticipated, or actively developing. Information obtained in one setting migrates—formally or informally—into another. Even when agencies insist on separation, personnel overlap, institutional memory persists, and investigative leads travel. The risk that compelled statements will influence criminal decision-making is not theoretical. It is structural.

This is why the Fifth Amendment analysis cannot turn on labels. Whether an interview is styled as administrative, disciplinary, or managerial is constitutionally irrelevant. What matters is substance: Was the statement compelled? Was there a realistic possibility of criminal exposure? Was refusal punished or threatened?

If the answer to those questions is yes, the Constitution is implicated—whether or not anyone acknowledges it in real time.

The consequences of ignoring this framework are severe. Compelled statements contaminate investigations. They force prosecutors into the impossible position of proving that later evidence was derived entirely from independent sources. They invite suppression, dismissal, and years of litigation. They undermine public confidence not only in disciplinary systems, but in criminal prosecutions themselves.

And they do so unnecessarily.

The Fifth Amendment does not prevent accountability. It does not create immunity by default. It does not shield misconduct. It simply requires the government to make a choice before it compels speech. Either the state preserves the option of criminal prosecution by respecting the right to remain silent—or it compels answers and accepts the constitutional consequence that those answers, and their fruits, may not be used criminally.

What the Constitution forbids is forcing the employee to make that choice himself.

This is the core problem that Garrity and its progeny were designed to resolve. Not to privilege public employees, but to restrain the government from using its dual role—as employer and sovereign—to extract incriminating statements it could not otherwise compel.

The Fifth Amendment is not suspended by a shield or a badge. It does not yield to internal policy manuals, investigative convenience, or bureaucratic sequencing. When the government demands answers under threat of job loss, constitutional law intervenes—whether the institution is prepared for that intervention or not.

Section I establishes the stakes. What follows traces how the courts resolved this tension, why those resolutions are routinely ignored in practice, and how New York law—particularly People v. Feerick—removes any plausible claim of uncertainty about the consequences of compelled speech.

II. The Foundation: Garrity v. New Jersey (1966)

The Prohibition on Coerced Self-Incrimination

The modern constitutional framework governing compelled statements by public employees begins with Garrity v. New Jersey. The case did not invent a new right. It enforced an old one in a context the State had attempted to exempt from constitutional scrutiny: internal questioning backed by the threat of job loss.

The holding was clear and narrow. Statements obtained from public employees under threat of termination are constitutionally compelled and may not be used against them in criminal proceedings. The Court rejected the State’s attempt to characterize such questioning as voluntary simply because no criminal charge had yet been filed. Coercion, the Court made clear, is defined by consequence—not by formality.

In Garrity, police officers were questioned during an investigation into ticket-fixing. They were warned that refusal to answer would result in removal from office. They answered. Those statements were later used to prosecute them criminally. The Supreme Court held that this arrangement violated the Fifth Amendment. When the State conditions continued employment on answering questions that may be incriminating, it has compelled testimony within the meaning of the Constitution.

The principle animating Garrity is foundational: the government may not force a person to choose between self-incrimination and livelihood. The Fifth Amendment forbids the State from imposing that dilemma, whether the pressure is applied in a courtroom, a police station, or a supervisor’s office.

For an officer sitting in an interview room, Garrity means this: the moment job loss is used to compel answers, the Constitution is already in play—long before any prosecutor files charges.

Importantly, Garrity framed compulsion as a constitutional event, not a procedural misstep. The violation occurs at the moment the State extracts statements under threat of punishment. The later use of those statements in criminal proceedings merely exposes the violation; it does not create it. This distinction matters, because it means constitutional harm does not depend on prosecutorial intent, timing, or even awareness. If the statements are compelled, the Fifth Amendment is already engaged.

At the same time, Garrity is often misunderstood—sometimes accidentally, sometimes opportunistically. It does not grant public employees blanket immunity from prosecution. It does not insulate misconduct from consequences. And it does not prevent employers from demanding accountability.

What Garrity does is far more precise.

First, Garrity does not bar administrative discipline. A public employer remains free to investigate misconduct, evaluate job performance, and impose discipline—including termination—based on lawful grounds. The Constitution does not require the government to tolerate misconduct simply because it might also be criminal.

Second, Garrity does not confer transactional immunity. The employee is not immunized from prosecution for the underlying conduct. The State may prosecute if it can do so without using the compelled statements or their derivatives. The Fifth Amendment protects against compelled self-incrimination, not against accountability.

Third, Garrity does not prohibit questioning. It regulates the conditions under which questioning occurs. The government must choose: either it preserves the option of criminal prosecution by respecting the employee’s right to remain silent, or it compels answers and accepts the constitutional consequence that those answers may not be used criminally.

This is the critical tradeoff Garrity enforces—and the one agencies routinely attempt to avoid.

Rather than making the choice openly, institutions often seek to collapse it. They compel statements without granting immunity, downplay criminal exposure, or rely on ambiguity to extract cooperation while preserving prosecutorial flexibility. Garrity exists precisely to prevent that maneuver. The Constitution does not permit the State to enjoy both advantages simultaneously.

The significance of Garrity is therefore structural. It recognizes that when the government acts as both employer and sovereign, it wields a uniquely coercive power. Without constitutional limits, that dual role would allow the State to accomplish indirectly—through threats to employment—what it could not compel directly through criminal process.

Garrity draws the line. It does not privilege public employees. It restrains government power.

What the decision leaves unresolved—and what subsequent cases were forced to clarify—is how the State may compel answers lawfully, what form immunity must take, and what happens when compelled statements contaminate later prosecutions. Those questions arise immediately in law enforcement, where administrative questioning and criminal exposure frequently intersect.

The next cases—Gardner v. Broderick and Uniformed Sanitation Men v. Commissioner—address that unresolved space. They explain when officers may be compelled to answer, what protections must be afforded, and why refusal to answer is constitutionally protected in some circumstances and punishable in others.

That clarification is where the doctrine becomes operational—and where agencies most often get it wrong.

III. Clarification and Limits: Gardner v. Broderick and Uniformed Sanitation Men v. Commissioner

What the Government Can—and Cannot—Compel

If Garrity established what the State may not do, Gardner v. Broderick and Uniformed Sanitation Men v. Commissioner explain what the State may do—provided it follows the Constitution rather than attempting to circumvent it.

These two 1968 decisions are often mischaracterized as retreating from Garrity. In fact, they do the opposite. They stabilize the doctrine by clarifying how the government can compel answers without violating the Fifth Amendment, and by drawing a line between lawful compulsion and unconstitutional coercion.

The core clarification is this: public employees—especially police officers—may be compelled to answer job-related questions, but only if the State removes the risk of criminal use. What the Constitution forbids is not accountability; it forbids forcing an employee to surrender the Fifth Amendment as the price of continued employment.

A. Gardner v. Broderick: No Forced Waiver of the Fifth Amendment

In Gardner, a New York City police officer was subpoenaed before a grand jury investigating police corruption. He was told he could keep his job only if he waived immunity and answered all questions. When he refused to waive his Fifth Amendment rights, he was terminated.

The Supreme Court held that termination unconstitutional.

The holding is precise and critical: the State may not fire a public employee merely for refusing to waive the Fifth Amendment privilege against self-incrimination. The problem was not that the City sought answers—it was that it demanded a constitutional surrender as a condition of employment.

The Court emphasized that the officer had not refused to answer job-related questions per se. He refused to sign away his constitutional protection. That distinction is dispositive. The Fifth Amendment protects against being compelled to give testimony that can be used criminally. It does not require the employee to gamble that protection in exchange for a paycheck.

Gardner therefore makes clear that invocation of the Fifth Amendment, standing alone, cannot be punished. An employee cannot be fired simply for insisting that compelled statements not be used criminally.

For an officer facing an internal interview, this means the Constitution protects the refusal to waive immunity—not silence itself—but only until lawful immunity is actually conferred.

B. Uniformed Sanitation Men: Compulsion Is Permitted—If Immunity Is Provided

Decided the same day, Uniformed Sanitation Men v. Commissioner addresses the other side of the equation.

There, sanitation workers were questioned about corruption in the department. They were discharged after refusing to answer questions, even though no immunity had been provided. The Supreme Court again sided with the employees—but clarified the rule that agencies often ignore.

The Court held that employees may be dismissed for refusing to answer questions specifically, directly, and narrowly related to their official duties—so long as they are not required to waive immunity from criminal use.

This is the fulcrum of the doctrine.

The government has a legitimate interest in demanding honesty and cooperation regarding job performance. But it must choose a constitutional path. It cannot compel answers while simultaneously preserving the option to use those answers in criminal prosecution. Once immunity from criminal use is assured, refusal to answer becomes insubordination, not constitutional protest.

Put simply:

• Refusal to answer job-related questions after immunity is conferred → discipline is permitted
• Refusal to waive Fifth Amendment rights or answer without immunity → discipline is prohibited

This distinction is not technical. It is constitutional.

C. What These Cases Actually Require

Taken together, Gardner and Uniformed Sanitation Men establish a workable framework that balances governmental authority with constitutional protection:

1. The questions must be narrowly tailored
   Fishing expeditions, generalized inquiries, or questions untethered from job performance exceed constitutional bounds.

2. The questions must relate directly to official duties
   Personal conduct is not automatically fair game simply because the subject is a police officer. The inquiry must concern employment-related conduct.

3. Immunity from criminal use must be assured
   Not promised vaguely. Not implied. Not left to later interpretation. The employee must be protected from having compelled statements used, directly or indirectly, in a criminal case.

When those conditions are met, the Fifth Amendment does not shield an employee from answering. Silence becomes sanctionable. Accountability is preserved.

When those conditions are not met, compulsion becomes coercion—and discipline becomes unconstitutional retaliation.

D. The Error Agencies Repeatedly Make

Despite the clarity of these decisions, agencies routinely collapse the distinction.

Officers are told interviews are “administrative” while criminal exposure plainly exists. Questioning proceeds without explicit immunity. Refusal is framed as non-cooperation. Discipline follows. The Fifth Amendment is treated as an inconvenience rather than a boundary.

Gardner and Uniformed Sanitation Men exist precisely to prevent that maneuver.

The Constitution does not allow the State to extract statements first and sort out immunity later. It does not permit ambiguity to function as leverage. And it does not tolerate discipline imposed to punish the assertion of constitutional rights.

The government must decide—before questioning begins—whether it is acting as employer or prosecutor. It may not act as both at once.

E. Why This Matters in Modern Policing

This framework is especially critical in law enforcement, where administrative investigations routinely overlap with criminal statutes, and where compelled statements can contaminate entire prosecutions if improperly obtained.

These cases ensure that accountability does not come at the cost of constitutional erosion. They allow departments to enforce standards without converting internal discipline into an end-run around the Fifth Amendment.

What they leave unresolved—and what becomes unavoidable in later doctrine—is what happens after immunity is granted: how broad that immunity must be, how derivative use is policed, and who bears the burden of proving independence in a subsequent prosecution.

That question is answered in Kastigar v. United States—and later refined in New York by People v. Feerick.

That is where the doctrine becomes unforgiving.

IV. The Immunity Standard: Kastigar v. United States (1972)

Use Immunity Is Enough—but the Burden Is Heavy

If Garrity defines when statements are compelled, and Gardner and Uniformed Sanitation Men define when compulsion is permissible, Kastigar v. United States defines the price the government must pay once it compels testimony.

That price is not transactional immunity. It is something far more exacting.

In Kastigar, the Supreme Court rejected the argument that the Fifth Amendment requires full transactional immunity—absolute immunity from prosecution for matters discussed. Instead, the Court held that “use and derivative use immunity” is constitutionally sufficient to compel testimony.

But that holding is routinely misunderstood.

Kastigar does not relax constitutional protection. It reallocates risk.

A. What Kastigar Actually Allows

The Court held that the government may compel testimony so long as it guarantees that:

1. The compelled statements themselves will not be used in a criminal case, and

2. No evidence derived directly or indirectly from those statements will be used.

This is not a narrow promise. It is a comprehensive prohibition.

“Derivative use” includes not only physical evidence or documents, but:

• Investigative leads

• Witness identifications

• Strategic decisions

• Charging theories

• Lines of questioning shaped by compelled disclosures

In other words, Kastigar recognizes a basic truth: information contaminates. Once compelled statements exist, they have the capacity to shape everything that follows.

B. The Critical Enforcement Rule: The Burden Shifts

Kastigar’s most consequential holding is not about immunity—it is about proof.

Once a defendant shows that testimony was compelled under a grant of immunity, the burden shifts entirely to the government. The prosecution must affirmatively demonstrate that every piece of evidence it seeks to use is derived from sources wholly independent of the compelled statements.

This is not a burden of persuasion by assurance. It is a burden of proof by evidence.

For the individual officer, this means that once compelled statements exist, the risk shifts entirely to the government—silence is no longer the danger, contamination is.

The government must show—not merely assert—that:

• Investigators were not exposed to compelled statements, or

• If exposed, that exposure played no role in the development of the case.

Speculation is insufficient. Good faith is irrelevant. Administrative convenience is immaterial.

The Supreme Court was explicit: the immunity must be “coextensive with the scope of the privilege.” Anything less fails the Fifth Amendment.

C. Why Kastigar Hearings Matter

This is why Kastigar hearings exist—and why they are not procedural formalities.

A Kastigar hearing is not about whether prosecutors intended to use compelled testimony. It is about whether the case can be proven to have been built without it.

These hearings are structural safeguards against what might otherwise become routine laundering:

• Compelled statements obtained administratively

• Informal sharing between investigators

• Prosecutors inheriting “clean” files that are not, in fact, clean

Absent rigorous enforcement, use immunity becomes illusory. The Fifth Amendment becomes conditional. And compelled testimony becomes a tool for criminal prosecution in everything but name.

Kastigar demands more than promises. It demands institutional discipline.

That demand becomes even sharper in jurisdictions—like New York—where police officers are subject to frequent administrative questioning that overlaps directly with criminal exposure.

Which brings the doctrine home.

V. New York’s Application: People v. Feerick

How Garrity Works—and Fails—in Practice

If Kastigar defines the federal constitutional standard, People v. Feerick defines how unforgiving that standard becomes when applied to real-world policing in New York.

Decided by the New York Court of Appeals, Feerick confirms a principle agencies often resist acknowledging: once departmental compulsion occurs, Garrity protections attach automatically—and the prosecution bears a heavy, affirmative burden to prove independence.

A. What Feerick Confirms

The Court of Appeals made several points unmistakably clear:

1. Compelled departmental testimony triggers Garrity protections
   An officer does not need to utter the word “immunity” for Garrity to apply. If questioning is compulsory and refusal carries employment consequences, the testimony is constitutionally compelled.

2. Prosecutors inherit the Kastigar burden
   Once compelled testimony exists, the prosecution must prove—affirmatively—that its evidence was derived from sources wholly independent of that testimony.

3. The inquiry is structural, not subjective
   The question is not whether prosecutors believe their case is clean. It is whether they can demonstrate, with evidence, that it is.

Feerick rejects the idea that internal discipline and criminal investigation can safely proceed in parallel without extraordinary care.

For the individual officer, Feerick means that once a compelled statement is taken, the constitutional risk does not belong to the employee—it belongs entirely to the government.

B. The Institutional Failures Feerick Exposes

What makes Feerick so instructive is not merely its holding, but the failures it identifies—failures that recur with alarming regularity:

• Parallel investigations sharing personnel or information
  When administrative investigators and criminal investigators communicate—formally or informally—the wall collapses.

• Inadequate segregation of compelled statements
  Compelled testimony is often memorialized, summarized, or referenced in ways that make true insulation impossible.

• Over-reliance on prosecutorial assurances
  Courts are told that prosecutors were “not influenced,” that they “did not rely,” or that they “built the case independently.” Feerick makes clear: assertions are not evidence.

• Administrative efficiency prioritized over constitutional rigor
  Departments move quickly to “get statements,” without accounting for the downstream consequences to criminal viability.

The result is predictable: cases that cannot survive Kastigar scrutiny, and prosecutions undone not by technicalities, but by constitutional contamination.

C. Feerick as a Warning—not an Anomaly

People v. Feerick is often treated as a cautionary tale for prosecutors. It is more accurately a warning to institutions.

The Fifth Amendment does not bend to workflow. It does not yield to internal convenience. And it does not tolerate “later sorting out” of immunity.

Once an officer is compelled to speak, the government assumes a constitutional debt. That debt must be paid in proof, discipline, and separation—or the prosecution fails.

This is not hostility to accountability. It is the price of choosing compulsion over silence.

Administrative efficiency cannot override constitutional rigor. And when agencies ignore that reality, Feerick shows exactly what happens.

VI. The NYPD Reality

How the Constitutional Line Gets Blurred in Practice

The constitutional framework governing compelled statements by public employees is not ambiguous. The Supreme Court has spent decades clarifying it. Yet inside police departments—particularly large, bureaucratic institutions like the NYPD—the clarity of the doctrine does not translate into clarity of practice. Instead, Garrity protections are routinely diluted, delayed, or functionally ignored through institutional habits that transform constitutional safeguards into afterthoughts.

The result is not open defiance of the Fifth Amendment, but something more dangerous: procedural drift. Officers are questioned first. Rights are sorted out later. And by the time criminal exposure becomes explicit, the constitutional damage has already been done.

This section explains how that drift occurs.

A. The Fiction of “Voluntary” Questioning

In theory, NYPD officers are questioned either voluntarily or under compulsion. In practice, that distinction collapses almost immediately.

Officers are summoned to interviews by supervisors or internal investigators. They are directed to appear at specific times and locations. The setting is formal. Notes are taken. Statements are memorialized. The questioning is detailed and probing. Yet the interview is often introduced with a single phrase: “This is voluntary.”

That label does not control the constitutional analysis.

The Supreme Court has never held that voluntariness turns on the words used by the employer. It turns on whether the employee reasonably believes that refusal carries professional consequences. In a paramilitary organization like the NYPD, where insubordination can itself be grounds for discipline, that belief is not speculative—it is structural.

An officer does not need to be explicitly told “answer or be fired” for compulsion to exist. It is enough that refusal would reasonably be understood as noncooperation, subject to later sanction. Courts have repeatedly recognized that implicit coercion within hierarchical institutions is still coercion.

Thus, many so-called “voluntary” NYPD interviews are constitutionally compelled as a matter of law, regardless of how they are labeled internally.

B. Ambiguous or Delayed Garrity Advisements

Even when Garrity warnings are eventually provided, they are frequently delivered too late or in language that obscures their legal effect.

It is not uncommon for officers to be questioned extensively before any advisement is given—particularly in the early stages of an incident, when investigators frame the interaction as a “preliminary inquiry” or “fact gathering.” By the time Garrity is mentioned, the officer has already provided potentially incriminating information.

This sequencing is constitutionally fatal.

That sequencing problem is especially consequential because NYPD Administrative Guide § 318-11 is designed—at least on paper—to formalize compelled interviews with an advisement structure that tracks Garrity/Kastigar principles. The practical failure is not that the policy is silent; it is that the department’s real-world sequencing often precedes the policy’s safeguards. Informal “fact gathering,” supervisory walk-throughs, and early questioning routinely occur before the § 318-11 advisement is delivered with clarity, before counsel is meaningfully situated, and before any true separation from criminal exposure is operationally enforced. In that gap, compelled information enters the system first—while constitutional consequences are treated as a downstream issue—creating exactly the contamination Kastigar and Feerick were meant to prevent.

Garrity protections attach at the moment compulsion occurs, not when the department chooses to acknowledge it. Once questioning proceeds under circumstances where refusal is not a realistic option, any statements obtained are immunized by operation of law. A delayed warning does not retroactively sanitize earlier compulsion.

Equally problematic are advisements that hedge. Officers may be told that statements are “for administrative purposes,” without an explicit assurance that they will not be used criminally. Or they may be told that cooperation is required, while immunity is described vaguely or conditionally.

That ambiguity recreates the very unconstitutional choice Garrity was designed to eliminate. An officer cannot meaningfully assess risk when the scope of immunity is unclear.

C. Supervisory Pressure and the Language of “Cooperation”

One of the most persistent ways Garrity is undermined is through supervisory framing.

Officers are told that answering questions will “help clear this up,” that refusal will “look bad,” or that cooperation will be “taken into account.” These statements are often delivered casually, without overt threats. But they are not constitutionally neutral.

That pressure is institutionalized by NYPD Administrative Guide § 304-10, which exposes members to severe discipline—including termination—for “false,” “misleading,” or even “inaccurate” statements made during official investigations. The procedure warns that evasive or strategically incomplete answers—including rote non-recollection depending on context—may be treated as misleading during official investigations, and it backs that warning with severe disciplinary exposure. When combined with ambiguous Garrity advisements, this policy transforms questioning into a constitutional trap: silence risks discipline, imperfect recall risks charges, and compelled speech risks criminal exposure. The Fifth Amendment does not permit the State to manufacture that dilemma through internal rules.

The Supreme Court has been clear: compulsion does not require menace. It requires pressure sufficient to overbear free choice. When supervisors tie participation to professional evaluation—explicitly or implicitly—they convert questioning into compelled testimony.

This is particularly acute in NYPD culture, where reputation, assignment, and advancement are deeply intertwined with perceptions of cooperation. An officer who invokes the Fifth Amendment risks being branded uncooperative long before any formal disciplinary process begins.

The Constitution does not permit that tradeoff.

D. Informal Questioning Before the Lines Are Drawn

Perhaps the most dangerous practice is informal questioning before the department decides whether an inquiry is administrative or criminal.

Following critical incidents, officers are often asked to “walk through what happened,” provide timelines, or answer preliminary questions before counsel is present and before Garrity is discussed. These statements are then incorporated—directly or indirectly—into investigative files.

Once compelled information enters the system, it cannot be unlearned. Even if later investigators are formally “walled off,” derivative contamination is almost inevitable. Leads are shaped. Theories are narrowed. Evidence is pursued with knowledge gained from compelled statements.

Kastigar does not tolerate this contamination. But institutions often proceed as though it can be managed through assurances rather than proof.

That assumption is wrong—and it is why prosecutions collapse when courts apply constitutional rigor.

VII. Fifth Amendment Breach Points

Where Constitutional Violations Actually Occur

If the Garrity line were honored in practice, most Fifth Amendment problems in police discipline would never arise. The governing rule is straightforward: the government may compel an officer to answer job-related questions only if it removes the risk that those compelled statements (and anything derived from them) will be used in a criminal case. The moment that risk is reintroduced—through ambiguity, delay, sharing, or derivative use—the constitutional system breaks.

That “break” does not usually happen in dramatic fashion. It happens in routine ways—through administrative habits that treat the Fifth Amendment as a downstream issue to be addressed later, when in fact the Fifth Amendment must be addressed first. This section isolates the main breach points where departments and prosecutors create unconstitutional exposure, often without even admitting to themselves that they have done so.

A. Failure to Give a Clear Garrity Advisement Before Compelled Questioning

The first breach point is sequencing. Too often, questioning begins with an institutional fiction: “We’re just trying to get your side,” or “This is preliminary.” The officer is asked for narrative detail, asked to account for decisions, asked to explain actions or omissions, asked about observations that may overlap with criminal statutes (assault, false statements, official misconduct, evidence tampering, obstruction). The interview is framed as informational rather than coercive. Yet the officer is directed to appear and knows that refusal carries professional consequences.

That is compulsion, whether the department labels it that way or not.

A constitutionally compliant system must clarify the status of the interview before the first substantive question. If the department intends to compel cooperation, it must say so and must make immunity explicit. If it does not intend to compel, then it must accept the officer’s right to decline without consequence.

Many of the most serious Garrity failures happen because neither choice is made cleanly. Departments proceed as though they can occupy a middle category: coercive in effect, but “voluntary” in language. That is precisely the unconstitutional choice Garrity prohibits. The Fifth Amendment does not turn on semantics. It turns on pressure and consequence.

B. Compelling Statements Before Immunity Is Explicitly Granted

The second breach point is closely related but distinct: compulsion without an explicit immunity grant.

In a properly structured interview, the officer is told—clearly and in writing—that answers are required as a condition of employment but will not be used against the officer in a criminal prosecution, and that refusal to answer job-related questions after that assurance may be grounds for discipline. That is the constitutional bargain recognized in the post-Garrity cases: the government trades away criminal use in exchange for workplace cooperation.

But in practice, officers are often compelled to speak while immunity is implied, hedged, or delayed. They may be told, “This is for administrative purposes,” which sounds protective but is not a constitutional guarantee. They may be told that the matter is “internal,” even as parallel criminal interest exists. They may be told that their statements will not be “shared,” even though the institution later shares them, or shares their fruits.

The constitutional problem is not merely that the officer is uncertain. The problem is structural: if immunity is not made explicit at the moment of compulsion, the state has not clearly removed the Fifth Amendment risk that Garrity exists to eliminate.

That uncertainty itself can be coercive. It forces an officer to gamble—either speak and risk criminal use, or remain silent and risk discipline. Garrity says the state cannot put the employee in that position.

C. Sharing Compelled Testimony with Criminal Investigators

The third breach point is the most legally explosive: the flow of compelled statements—directly or indirectly—to criminal investigators or prosecutors.

In theory, departments can maintain a wall: administrative investigators handle compelled statements; criminal investigators build cases without exposure to those statements. In practice, institutional ecosystems are not cleanly separable. Personnel overlap. Units coordinate. Information is exchanged. Leadership receives briefings. Case narratives are shared informally. Even a single exposure can contaminate an entire criminal investigation because prosecutors then bear the heavy Kastigar burden of proving independence.

The danger is not limited to handing over a transcript. It includes:

• summarizing the officer’s compelled account in an email;

• briefing a detective squad or DA liaison on “what the officer said”;

• providing a timeline derived from compelled statements;

• flagging locations, witnesses, or evidence based on compelled answers;

• allowing compelled materials to enter a shared case management system.

Any of those actions can create derivative use.

And this is the point many institutions misunderstand: Kastigar does not require the prosecution to show that it did not intend to use the compelled statements. It requires the prosecution to show that it did not use them at all—not directly, not indirectly, not as a lead, not as a framing device, not as a roadmap.

If compelled information enters the criminal bloodstream, the government may later find itself unable to prove the clean sourcing of its evidence. That is not “technicality.” That is constitutional design.

D. Using Derivative Leads Without Kastigar Proof

The fourth breach point is derivative use—the quiet laundering of compelled testimony into “independent” evidence.

This is where most constitutional violations actually live. Institutions rarely admit, “We used the compelled statement.” Instead, they build their criminal case around evidence that appears, on the surface, to be independent: a witness interview, a recovered object, a surveillance video, a phone record, an expert analysis. The problem is the path that led to those items.

If an administrative compelled statement told investigators where to look, whom to interview, what to ask, what to seize, or what theory to pursue, then the later evidence may be derivative—even if the evidence is real and admissible in the abstract. The Fifth Amendment issue is not whether the evidence is reliable; it is whether the evidence was obtained through an unconstitutional chain.

This is why Kastigar is a discipline of provenance. It forces the government to document: How did you learn this? When? From whom? With what prior exposure?

When institutions are sloppy about documenting independence contemporaneously—when they rely on generalized assurances or post hoc narratives—Kastigar becomes a trap. The prosecution cannot meet its burden with confidence because the record cannot show clean sourcing.

E. “Parallel” Investigations That Aren’t Parallel in Fact

The fifth breach point is the pretense of parallelism. Departments and prosecutors often claim that administrative and criminal investigations proceed separately. Yet separation is not a label; it is a set of controlled conditions. True separation requires:

• distinct personnel (no overlap);

• distinct files and storage systems;

• controlled access logs;

• explicit written protocols;

• briefing discipline;

• and, critically, leadership discipline (no cross-channel sharing by supervisors).

Without those controls, parallel investigations become a single investigation with two faces. Administrative compulsion becomes the information engine; criminal prosecution becomes the downstream product.

That is precisely what the Fifth Amendment forbids.

F. The Failure Mode: “We Didn’t Use It” Is Not a Defense

Institutions often fall back on a familiar refrain: We didn’t use the compelled statements in the criminal case.

That is not the legal standard.

The standard is whether any evidence was derived from compelled statements, and the burden is on the government to prove independence. In high-profile cases, courts will not accept comfort language. They will demand an evidentiary showing. And where institutional practices were informal, the government’s proof fails.

This is the deepest takeaway of the Garrity/Kastigar/Feerick line: constitutional compliance is not a matter of good intentions. It is a matter of architecture. If the system is not built to prevent contamination, contamination becomes inevitable—and the Fifth Amendment breach becomes predictable.

Section VII therefore identifies the practical truth: Fifth Amendment violations are rarely a single moment. They are a chain of institutional shortcuts—question first, advise later; compel without clarity; share informally; chase derivative leads; then insist nothing was “used.” That is not compliance. It is constitutional drift.

What follows is not another warning. It is a blueprint for lawful compulsion.

VIII. What Lawful Compulsion Requires

A Constitutionally Compliant Checklist—and Why Each Element Exists

The phrase “Garrity warning” is often used as if it were a talisman—say the words, check the box, proceed. That is the wrong mental model. Garrity is not a script. It is a constitutional boundary: if the state compels an officer to speak, it must build a system that prevents compelled speech from becoming a criminal tool.

This section sets out what lawful compulsion actually requires. Not as aspirational best practices, but as structural necessities derived from the doctrine itself. Each requirement exists because courts have seen what happens when it is missing.

A. A Clear, Written Advisement Before Any Substantive Questions

The first requirement is temporal and procedural: no substantive questioning begins until the status is clarified in writing.

If the interview is voluntary, the officer must be told that refusal will not be used as a basis for discipline and that the officer may consult counsel. If the interview is compelled, the officer must be told that refusal to answer job-related questions may lead to discipline, but that answers are immunized from criminal use.

This is not formalism; it is the mechanism by which the unconstitutional choice is removed. When departments begin questioning and “sort it out later,” they reintroduce coercion and uncertainty. A written advisement up front prevents later disputes about whether statements were compelled and whether the officer understood the bargain.

It also protects the institution by creating a clean record. The Constitution, in this context, rewards institutions that build documentation discipline at the point of compulsion rather than after litigation begins.

B. An Explicit Grant of Use and Derivative-Use Immunity

The second requirement flows directly from Kastigar: the immunity must cover both use and derivative use.

This is where institutions sometimes misunderstand the difference between administrative assurances and constitutional immunity. Saying “this is for administrative purposes” is not enough. The officer must be told, explicitly, that:

1. the statement will not be used against the officer in a criminal prosecution; and

2. no evidence derived from the statement will be used.

That second component is not optional. It is the core of Kastigar. Without derivative-use immunity, the government could compel testimony, then quietly build a criminal case using the roadmap the officer was forced to provide. Kastigar exists to prevent precisely that laundering.

C. Strict Separation Between Administrative and Criminal Teams

The third requirement is structural: a real wall, not a rhetorical one.

A constitutional wall requires:

• no overlap in personnel;

• no shared supervisors participating in both tracks;

• separate case files with access controls;

• written protocols prohibiting cross-briefing;

• documented “clean team” assignments for any criminal inquiry;

• and a clear chain of custody for evidence, showing when and how it was obtained.

The purpose is not bureaucratic elegance. The purpose is future proof: if a criminal case proceeds, the government must be able to prove that its evidence was developed independently. That proof is only credible if separation was designed in advance and enforced in real time.

D. Contemporaneous Documentation of Independent Evidence

The fourth requirement is evidentiary discipline: every criminal lead must be traceable to a source independent of compelled statements.

If the government waits until charges are filed to reconstruct its independence narrative, it will fail. Courts are skeptical of post hoc explanations because they are easy to manufacture and hard to disprove. Contemporaneous documentation—notes, reports, timestamps, source attribution—creates an auditable record.

This is especially important in police cases because investigations are iterative: theories evolve, evidence is reevaluated, witnesses are reinterviewed. Without documentation discipline, derivative contamination becomes impossible to rule out. Kastigar then becomes not a hearing you “get through,” but a burden you cannot carry.

E. Automatic Kastigar Review When Criminal Charges Are Contemplated

The final requirement is procedural governance: Kastigar review cannot be optional or ad hoc.

If an agency compels statements in an administrative investigation and later contemplates criminal charges against the same officer, the institution should presume that a Kastigar issue exists and should structure an automatic review process:

• identification of all compelled materials (transcripts, summaries, notes);

• identification of all personnel exposed to those materials;

• assignment of a clean prosecution/investigation team;

• a written proffer of independent sources for each item of evidence;

• a mechanism to litigate these issues before trial, not after.

This is not indulgence. It is constitutional realism. Once compelled statements exist, the government’s risk is not merely suppression—it is collapse of the prosecution if it cannot demonstrate clean sourcing. Automatic Kastigar protocols are therefore not only rights-protective; they are institution-protective.

F. The Core Principle: Rights Require Systems, Not Promises

If there is a single through-line across Garrity, Gardner, Uniformed Sanitation Men, Kastigar, and Feerick, it is this: the Constitution does not trust informal assurances.

It demands structure because structure is what prevents coercive power from becoming self-justifying. In law enforcement agencies, where the same incident can generate administrative discipline, civil liability, and criminal exposure, the risk of cross-contamination is not theoretical. It is the default. Only deliberate architecture prevents it.

That is why lawful compulsion is not a checklist you paste into a policy manual. It is an operating system.

And that is the larger point of this thought-piece: the Fifth Amendment in police discipline is not a niche doctrinal problem. It is a test of whether institutions can handle internal accountability without turning compelled cooperation into a prosecutorial weapon—or, conversely, without using “accountability” as a pretext to coerce statements while evading constitutional limits.

In the next section, the analysis should move from compliance design to institutional incentives: why agencies resist building these walls, why prosecutors sometimes prefer ambiguity, and how “public integrity” narratives can be used to rationalize constitutional shortcuts. Because the legal doctrine is settled. The real fight is whether the system will implement it.

IX. Why This Matters Beyond Officers

Systemic Legitimacy, Institutional Integrity, and Public Trust

It is tempting—particularly in public discourse—to frame Garrity and Fifth Amendment disputes as matters of officer privilege. That framing is not just incomplete; it is structurally wrong. The constitutional limits on compelled testimony in police discipline are not designed to shield officers from accountability. They are designed to preserve the legitimacy of accountability itself.

When departments shortcut these protections, the harm does not stop with the officer being questioned. It radiates outward—into prosecutions, civil litigation, public confidence, and ultimately the credibility of the institutions charged with enforcing the law.

A. Constitutional Shortcuts Corrode Prosecutions at the Root

The most immediate consequence of unlawful compulsion is prosecutorial fragility. A criminal case touched—directly or indirectly—by compelled testimony is not merely vulnerable; it is constitutionally compromised. The issue is not whether the defendant is sympathetic or whether the alleged conduct is serious. The issue is whether the government can meet its burden of proving that its evidence is untainted.

When departments compel statements without immunity clarity, share information informally, or fail to document independent sourcing, they do not strengthen criminal cases—they sabotage them. They create suppression risks, Kastigar failures, and appellate exposure that can undo years of investigative work.

This is not hypothetical. Courts have repeatedly made clear that confidence is not proof. Assurances that investigators “didn’t rely” on compelled material mean nothing if the record cannot demonstrate clean separation. Once contamination is plausible, the prosecution’s burden becomes nearly insurmountable.

In that sense, the Fifth Amendment does not obstruct justice; it enforces evidentiary discipline. It demands that the government build cases the right way, from the beginning, rather than retrofitting constitutional compliance after the fact.

B. Unlawful Compulsion Poisons Cases Before Trial Ever Begins

The damage caused by unlawful compulsion often occurs long before a judge ever hears a suppression motion. It occurs at the charging stage, in plea negotiations, in declination decisions, and in the quiet abandonment of cases deemed “too risky” to pursue.

When prosecutors inherit cases built on compromised investigative practices, they face a dilemma of their own: proceed and risk collapse, or retreat and allow potentially serious misconduct to go unadjudicated. Either outcome erodes confidence—in the system’s fairness, in its competence, and in its ability to police itself.

This dynamic is corrosive not only for defendants but for victims, communities, and the public at large. When cases implode due to constitutional violations, the narrative often becomes one of “technicalities” rather than institutional failure. That mischaracterization further distorts public understanding, framing constitutional enforcement as obstruction rather than as the mechanism that preserves legitimacy.

C. Courts Become the Backstop When Institutions Fail Themselves

A recurring theme across Garrity, Kastigar, Feerick, and their progeny is institutional abdication. The doctrine is settled. The rules are clear. Yet courts are repeatedly forced to intervene—not because the law is ambiguous, but because compliance is inconvenient.

When departments blur the line between administrative and criminal inquiry, they effectively delegate constitutional boundary-policing to judges. That is not how the system is designed to function. Courts are reactive institutions. They correct violations after harm has occurred. They are not meant to be the primary architects of investigative integrity.

Every time a court suppresses evidence, dismisses charges, or rebukes a department for Fifth Amendment violations, it is doing work that should have been done internally—by supervisors, legal bureaus, inspectors general, and prosecutors exercising discipline at the front end.

This pattern mirrors a broader institutional failure: when internal governance mechanisms are weak, constitutional litigation becomes the only remaining check. That is not a sign of robust accountability. It is a sign that accountability arrived too late.

D. The Fifth Amendment Protects Institutions From Their Own Incentives

Perhaps the most underappreciated function of the Fifth Amendment in this context is that it protects institutions from themselves.

Police departments face intense pressure to resolve incidents quickly, to demonstrate responsiveness, to discipline misconduct, and to cooperate with prosecutors. Prosecutors face pressure to build cases efficiently, to rely on familiar investigative partners, and to avoid delays. These pressures are real—and they are precisely why constitutional guardrails exist.

Without Garrity and Kastigar, the path of least resistance would always be to compel first and sort out consequences later. The Fifth Amendment blocks that instinct. It forces institutions to choose: either compel cooperation and forgo criminal use, or preserve criminal prosecution and accept silence. What it forbids is trying to have both.

That prohibition is not anti-accountability. It is anti-coercion. And by preventing the government from leveraging employment power to extract criminal advantage, the Constitution preserves the integrity of both systems—administrative discipline and criminal justice.

E. Public Trust Is Built on Process, Not Outcomes

Finally, this doctrine matters because public trust does not rest on whether particular officers are punished or acquitted. It rests on whether the process is credible.

When the public sees cases collapse due to constitutional violations, confidence erodes—not because courts enforced rights, but because institutions failed to respect them in the first place. When departments appear to cut corners internally, it reinforces cynicism about whether accountability is genuine or performative.

A system that respects the Fifth Amendment in police discipline sends a clear signal: accountability is not a shortcut; it is a discipline. And discipline, when done lawfully, strengthens legitimacy rather than undermining it.

X. Conclusion

Compulsion Without Immunity Is Not Accountability—It Is Unconstitutional Leverage

This analysis ends where the doctrine has always been clear.

The Constitution does not forbid police departments from disciplining officers. It does not forbid internal investigations. It does not forbid compulsion in the employment context. What it forbids is forcing a public employee to surrender constitutional protection as the price of keeping a job.

That line is not new. It was drawn in Garrity, clarified in Gardner and Uniformed Sanitation Men, fortified in Kastigar, and enforced—repeatedly—in cases like Feerick. The problem has never been doctrinal uncertainty. The problem has been institutional resistance to living within that line.

A. Accountability and Coercion Are Not the Same Thing

True accountability is deliberate. It is structured. It is lawful. Coercion, by contrast, is expedient. It relies on imbalance of power rather than rigor of process. When departments compel statements without immunity clarity, or blur administrative and criminal lines, they are not holding officers accountable—they are leveraging authority in ways the Constitution forbids.

That leverage may feel effective in the moment. It may produce statements, narratives, and apparent cooperation. But it does so at the cost of legitimacy. And that cost is eventually paid—through suppression, dismissal, reversal, or public loss of confidence.

B. The Constitutional Bargain Is Simple—and Non-Negotiable

The Fifth Amendment offers a straightforward bargain to government employers:

• If you want answers for workplace discipline, you may compel them—but you must relinquish criminal use.

• If you want criminal prosecution, you may pursue it—but you must accept silence.

What you may not do is compel cooperation while keeping criminal leverage in reserve. That is not balance. It is unconstitutional pressure.

Departments that ignore this bargain do not gain flexibility. They incur risk. And when that risk materializes, courts will not rescue them from the consequences of their own shortcuts.

C. Courts Will Enforce the Boundary When Institutions Will Not

History shows that when departments fail to police this line internally, courts will enforce it externally. That enforcement is not hostile to policing. It is a corrective response to institutional drift.

But judicial intervention is a blunt instrument. It arrives late. It remedies harm rather than preventing it. The goal should not be to survive suppression hearings. The goal should be to design systems that never require them.

D. The Broader Lesson

The Fifth Amendment, in this context, is not an obstacle to reform. It is a measure of seriousness.

Institutions that respect it demonstrate that they can investigate themselves without sacrificing constitutional values. Institutions that circumvent it signal something else: that expedience matters more than legitimacy, and outcome matters more than process.

In the long arc of public trust, that distinction matters.

Compulsion without immunity is not accountability.
It is unconstitutional leverage.

And when departments cross that line, courts will draw it back—for officers, for defendants, and for the integrity of the system itself.
