Police Interrogation

Police Interrogation

Police interrogation is one of the most important stages of a criminal investigation because it directly concerns the government’s attempt to obtain information, admissions, or confessions from a person suspected of criminal conduct. Unlike a search, which ordinarily concerns physical or digital evidence, interrogation seeks evidence through the suspect’s own words.

Police questioning can occur long before a formal charge is filed. An officer may ask questions at the scene of an incident, during an investigative detention, at a police station, after an arrest, or while a suspect is being transported or held in custody. The constitutional rules governing that questioning depend heavily on the circumstances—especially whether the person is in custody and whether the police are engaged in interrogation.

The distinction is important because not every conversation between police and a suspect is a custodial interrogation. At the same time, interrogation under constitutional law is broader than simply asking a direct question. Under the Supreme Court’s interpretation of Miranda v. Arizona and Rhode Island v. Innis, interrogation can include the functional equivalent of questioning: words or actions that police should know are reasonably likely to elicit an incriminating response.

For a useful overview of the subject, see Cornell Law School’s Wex definition of interrogation.

What Is Police Interrogation?

Police interrogation is the questioning of a person by law enforcement for the purpose of investigating possible criminal activity and obtaining information that may be relevant to the investigation.

The word “interrogation” can suggest a formal interview room, a detective asking questions under bright lights, or a recorded confession. Legally, however, the concept is broader.

Police interrogation can include:

• direct questions about an alleged crime;
• questions about a person’s whereabouts;
• questions designed to establish knowledge of criminal conduct;
• confrontational questioning;
• requests for explanations or admissions;
• certain psychological techniques;
• statements or conduct that function as the equivalent of direct questioning.

The legal significance of an interrogation depends not merely on what the officer intended but also on the circumstances in which the police conduct occurred.

A person who voluntarily approaches an officer and begins talking is not necessarily being interrogated. Similarly, an officer may ask preliminary questions during a consensual encounter without triggering the constitutional rules governing custodial interrogation.

The central question becomes more serious when the person is in custody.

Interrogation and Custodial Interrogation

The constitutional rules associated with Miranda are principally concerned with custodial interrogation.

A useful way to understand the concept is to separate two questions:

1. Is the person in custody?
2. Is the person being interrogated?

Both generally matter for the Miranda framework.

A person can be interrogated without being in custody. For example, police may question a person during a voluntary interview in which the person remains free to leave. Miranda’s special custodial safeguards generally do not apply merely because police are asking questions.

Conversely, a person can be in custody without being interrogated. A person who has been arrested and placed in a holding cell is in custody, but if officers are not questioning the person or engaging in conduct that constitutes interrogation, the Miranda interrogation requirement is not automatically triggered.

It is the combination of custody plus interrogation that creates the classic custodial-interrogation situation.

Cornell’s Wex describes custodial interrogation as questioning of a detained person by law enforcement in connection with a criminal investigation and explains that the Miranda safeguards apply to custodial interrogation.

What Does “Custody” Mean?

Custody is not limited to the formal words “you are under arrest.”

The constitutional inquiry generally asks whether, considering the circumstances, the person’s freedom of action has been restrained to a degree comparable to a formal arrest.

This means that an officer’s failure to announce an arrest does not necessarily prevent a situation from being custodial.

Courts examine the objective circumstances surrounding the encounter, including matters such as:

• where the questioning occurs;
• whether the person was told that they were free to leave;
• the number of officers present;
• whether officers displayed weapons;
• the use of physical restraints;
• the length and character of the questioning;
• whether the person was transported to another location;
• the degree of police control over the person’s movements;
• whether the person was formally arrested.

The inquiry is generally objective rather than based solely on the officer’s subjective intentions.

A person questioned casually on a public street may not be in custody. The same person, after being handcuffed, placed in a police vehicle, and transported to a station, may plainly be in custody.

The fact that questioning occurs inside a police station also does not automatically establish custody. The surrounding circumstances still matter.

What Does “Interrogation” Mean?

The Supreme Court addressed the meaning of interrogation under Miranda in Rhode Island v. Innis.

The basic concept includes express questioning and its functional equivalent. The functional equivalent consists of police words or actions, other than those normally attendant to arrest and custody, that officers should know are reasonably likely to elicit an incriminating response from the suspect.

This distinction is important.

Suppose an officer asks:

“Where did you put the weapon?”

That is obviously express questioning.

But suppose an officer does not directly ask the suspect where the weapon is and instead deliberately engages in conduct that the officer should know is reasonably likely to cause the suspect to reveal its location. Depending on the circumstances, that conduct may constitute interrogation even though the officer never asked a conventional question.

Thus, interrogation is not determined simply by looking for a question mark.

Direct Questioning

The easiest cases involve direct questioning.

An officer who asks a person in custody:

• “Did you commit the robbery?”
• “Where were you last night?”
• “Who else was with you?”
• “Where is the weapon?”
• “What happened inside the house?”

is plainly engaging in questioning.

If the questioning occurs while the person is in custody, Miranda becomes relevant.

The fact that the questions appear routine does not necessarily change their legal character. A question can constitute interrogation even when it is phrased politely, indirectly, or conversationally.

The Functional Equivalent of Questioning

The functional-equivalent doctrine prevents police from avoiding constitutional safeguards simply by replacing a question with a calculated statement or action.

In Rhode Island v. Innis, the Supreme Court explained that interrogation includes not only express questioning but also its functional equivalent. The inquiry focuses on whether police words or actions were reasonably likely to elicit an incriminating response.

The doctrine therefore does not mean that every statement made by an officer to a suspect constitutes interrogation.

Police officers can speak to people in custody. They can give ordinary instructions, explain procedures, communicate logistical information, and perform actions normally associated with custody.

The critical issue is whether the police conduct crosses the line into conduct that should reasonably be expected to produce an incriminating response.

Police Statements Are Not Always Interrogation

This limitation is important because otherwise virtually every interaction between police and a suspect would become an interrogation.

For example, officers may need to say:

• “Stand here.”
• “We are taking you to the station.”
• “You will be photographed.”
• “Put your hands behind your back.”
• “We are going to begin the booking process.”

These statements ordinarily concern the mechanics of arrest and custody rather than an attempt to obtain incriminating information.

Likewise, a spontaneous statement made by a suspect is not necessarily the product of interrogation.

The Supreme Court has recognized that volunteered statements are not automatically barred merely because the person is in police custody.

Voluntary Statements and Interrogated Statements

The distinction between volunteered statements and statements produced through interrogation is fundamental.

Imagine that a suspect has been arrested and is sitting in a police vehicle. Without being asked anything, the suspect suddenly says:

“I shouldn’t have gone into that house.”

That statement may be admissible even though the suspect is in custody, because custody by itself does not transform every statement into a Miranda violation.

Now imagine that an officer asks:

“Why did you go into the house?”

If the suspect is in custody, the officer has engaged in express questioning.

The constitutional analysis is therefore not simply:

Was the person in custody?

It is:

Was the person in custody subjected to interrogation?

Miranda and Police Interrogation

Miranda v. Arizona established constitutional safeguards for custodial interrogation.

The Supreme Court held that before custodial interrogation, police must inform the person of certain constitutional rights, including the right to remain silent and the right to have an attorney present during questioning, with appointed counsel available for an indigent person in the circumstances specified by the constitutional framework.

These warnings are commonly known as Miranda warnings.

The purpose is closely connected to the Fifth Amendment privilege against compelled self-incrimination.

The Fifth Amendment protects individuals from being compelled to provide testimonial evidence that could incriminate them. That protection is particularly important during custodial police questioning because the setting of custody can create significant psychological pressure to answer questions.

Miranda therefore establishes a procedural safeguard intended to protect the underlying constitutional privilege during custodial interrogation.

Miranda Does Not Apply to Every Police Question

A common misconception is that police must give Miranda warnings whenever they ask someone about a crime.

That is not the rule.

Miranda is primarily concerned with custodial interrogation.

An officer may ask questions during a voluntary encounter without necessarily giving Miranda warnings. Likewise, questioning conducted before custody ordinarily does not trigger the Miranda requirement merely because the person is a suspect.

For example, an officer investigating a burglary might approach a person on the street and ask:

“Did you see anyone enter that building last night?”

If the encounter remains voluntary and the person is not in custody, the question does not automatically become custodial interrogation.

The constitutional analysis changes if the officer later detains or arrests the person and continues questioning under custodial circumstances.

Police Interrogation During an Investigative Stop

An investigative detention occupies an important middle ground.

A person temporarily detained under the Fourth Amendment is not necessarily in Miranda custody simply because the detention is a seizure.

A lawful traffic stop, for example, involves a temporary restraint on freedom of movement. But an ordinary traffic stop does not automatically constitute custodial interrogation.

The precise circumstances matter.

The Fourth Amendment question is whether the detention is lawful and appropriately limited. The Fifth Amendment question is whether the person is subjected to custodial interrogation.

These are related but separate constitutional inquiries.

This distinction prevents the concepts of reasonable suspicion, custody, interrogation, and Miranda from being treated as interchangeable.

Interrogation After Arrest

After an arrest, the possibility of custodial interrogation becomes much more direct.

Police may need to ask questions for legitimate administrative purposes, such as identifying the arrested person or processing the arrest. Other questions may seek evidence concerning the suspected crime.

The constitutional consequences depend on what the officers are asking and why the interaction qualifies as interrogation.

An arrest therefore does not mean that police can never speak to the person. It means that when custodial interrogation begins, the Miranda safeguards become relevant.

Police Interrogation Techniques

Police investigations may involve a variety of questioning techniques.

Officers may:

• ask the suspect to describe events in chronological order;
• confront the suspect with evidence;
• ask about inconsistencies;
• ask the suspect to explain another person’s account;
• challenge the suspect’s version of events;
• use silence or pauses;
• present information already obtained during the investigation;
• ask follow-up questions based on previous answers.

Not every psychological technique is unconstitutional.

The Constitution does not prohibit police from attempting to persuade a suspect to speak. The critical constitutional boundaries include whether the questioning is custodial, whether Miranda applies, whether the suspect’s rights are properly respected, and whether the resulting statement is voluntary.

Coercive Interrogation and Voluntariness

Miranda is not the only constitutional limitation on police interrogation.

Even when Miranda is not directly implicated, a confession or statement may raise a separate voluntariness issue.

The Due Process Clause prohibits confessions obtained through unconstitutional coercion.

This makes an important distinction:

A Miranda violation and an involuntary confession are not necessarily the same constitutional problem.

A statement can be challenged because police failed to comply with Miranda requirements. A statement can also be challenged because it was obtained through coercive conduct so extreme that the statement was constitutionally involuntary.

Factors relevant to voluntariness can include the nature of police conduct and the circumstances surrounding the suspect’s decision to speak.

Physical violence, extreme threats, overwhelming psychological coercion, or other forms of unconstitutional pressure can create a fundamentally different issue from ordinary police persuasion.

The Role of Psychological Pressure

Police interrogation can be psychologically demanding without necessarily being unconstitutional.

Investigators may confront suspects with evidence, challenge their credibility, ask repeated questions, or encourage them to provide an explanation.

The constitutional question is not whether the interrogation was uncomfortable.

Rather, courts must determine whether constitutional safeguards were required and whether the resulting statement was obtained in a constitutionally permissible manner.

This is one reason courts examine the circumstances of interrogation rather than relying on a single factor.

The Right to Remain Silent

One of the most recognizable protections associated with police interrogation is the right to remain silent.

The privilege against self-incrimination protects individuals against compelled testimonial self-incrimination. Miranda provides a procedural mechanism for protecting that privilege during custodial interrogation.

A suspect therefore does not have a constitutional obligation to provide police with a confession merely because officers ask questions.

The precise rules concerning invocation of Miranda rights are more complicated than simply remaining silent, however. Courts have addressed whether a suspect has adequately invoked the right to silence and how police may proceed afterward.

Those issues are best treated separately from the basic definition of police interrogation.

The Right to Counsel During Interrogation

The presence of counsel can fundamentally change the interrogation process.

Miranda requires police to advise a person in custodial interrogation of the right to have an attorney present during questioning.

Once the right to counsel is properly invoked under the applicable Miranda rules, police questioning is subject to significant restrictions.

The Supreme Court has repeatedly distinguished between the constitutional right to counsel arising under Miranda and the separate Sixth Amendment right to counsel that attaches at a different stage of criminal proceedings.

That distinction matters because the Fifth Amendment/Miranda right and Sixth Amendment right to counsel do not arise under identical circumstances.

Police Interrogation and the Sixth Amendment

The Sixth Amendment provides a separate constitutional protection concerning the assistance of counsel.

Its right-to-counsel protections generally attach after the initiation of adversarial judicial proceedings and are offense-specific.

Miranda’s Fifth Amendment protection against compelled self-incrimination, by contrast, is concerned with custodial interrogation and applies before the Sixth Amendment right necessarily arises.

Consequently, the fact that a person has an attorney in connection with one criminal matter does not automatically mean that police cannot question the person about every possible offense.

The distinction between these two rights is essential to understanding modern criminal procedure.

Statements Obtained Without Miranda Warnings

If police conduct a custodial interrogation without the required Miranda safeguards, the resulting statement may be subject to exclusion from the prosecution’s case under the applicable constitutional rules.

The consequence is therefore generally evidentiary: the government may face restrictions on using the statement at trial.

Cornell’s discussion of the exclusionary rule explains that Miranda established protections against the use of improperly elicited self-incriminating statements obtained in violation of the Fifth Amendment.

But the consequences of a Miranda violation are more nuanced than the simple statement “the evidence disappears.”

The Supreme Court has distinguished between different uses of statements, derivative physical evidence, impeachment use, and genuinely coerced statements. The admissibility of a particular statement or derivative evidence therefore requires careful analysis rather than an automatic conclusion.

A Miranda Violation Is Not Automatically the Same as Coercion

This distinction deserves emphasis.

Suppose police fail to provide Miranda warnings before questioning a person in custody, and the person makes an incriminating statement.

That does not necessarily mean the statement was physically or psychologically coerced.

A Miranda violation concerns the failure to provide the constitutionally required procedural safeguards before custodial interrogation.

An involuntary confession involves a different constitutional problem: the government obtained the statement through unconstitutional coercion.

The distinction can affect the remedies available and whether derivative evidence may be used.

Physical Evidence Derived From Interrogation

Another complicated issue arises when a suspect’s statement leads police to physical evidence.

For example, suppose police obtain an incriminating statement without complying with Miranda, and the statement leads officers to a hidden weapon.

The constitutional treatment of the statement and the weapon may differ.

The Supreme Court has addressed circumstances in which physical evidence derived from a Miranda violation may nevertheless be admissible, while genuinely coerced statements raise more serious constitutional concerns.

This is one reason courts analyze the precise constitutional defect rather than treating every interrogation problem as identical.

Interrogation After a Suspect Requests an Attorney

When a suspect invokes the right to counsel under Miranda, the rules governing subsequent questioning become particularly important.

In Rhode Island v. Innis, the Supreme Court considered whether police conduct following a request for counsel constituted interrogation. The Court explained that interrogation includes express questioning and its functional equivalent, focusing on whether police conduct was reasonably likely to elicit an incriminating response.

Thus, police cannot necessarily avoid an invoked right to counsel merely by replacing a direct question with an indirect conversational technique.

The precise rules governing invocation, reinitiation, and subsequent questioning are sufficiently important to warrant separate treatment in an article devoted specifically to Miranda Rights and Invocation.

Spontaneous Statements

A suspect may sometimes make an incriminating statement without being asked a question.

For example, an arrested person may spontaneously say:

“I know where the stolen property is.”

If officers did not prompt the statement through interrogation, the mere fact that the person was in custody does not automatically make the statement inadmissible under Miranda.

The Supreme Court has recognized that volunteered statements are not automatically prohibited simply because the speaker is in custody.

The critical issue is therefore whether the statement was genuinely volunteered or was instead the product of police interrogation.

Recording Police Interrogations

Modern interrogations are frequently recorded through audio or video.

Recording can provide evidence concerning:

• whether Miranda warnings were given;
• what the suspect was told;
• whether the suspect invoked a right;
• whether questioning continued;
• what questions were asked;
• whether the suspect appeared to understand the warnings;
• whether the statement was spontaneous;
• how the interrogation developed.

Recording does not itself determine whether an interrogation was constitutional, but it can provide an important factual record for courts evaluating disputed events.

Federal and state practices concerning recording may differ, and some jurisdictions have adopted rules concerning electronic recording of custodial interrogations.

Juveniles and Police Interrogation

Interrogating a juvenile raises additional concerns.

Children and adolescents may respond differently to authority, may have less understanding of legal rights, and may be more susceptible to pressure than adults.

The constitutional analysis still involves Miranda and voluntariness principles, but courts may consider age and other circumstances when evaluating whether constitutional requirements were satisfied.

State law can also provide additional protections for juveniles beyond the federal constitutional minimum.

Consequently, juvenile interrogation should not be analyzed simply by applying the same practical assumptions used for an adult suspect.

Interrogation of Suspects Who Do Not Speak English

Language and comprehension can also become important.

A Miranda warning must effectively communicate the relevant rights. If a person does not understand the language in which the warning is given, the mere recitation of words may not resolve the constitutional issue.

Courts may therefore examine the person’s comprehension and the totality of the circumstances surrounding a purported waiver.

Again, the precise requirements can vary according to the circumstances and applicable federal or state law.

Police Interrogation and False Confessions

One of the most serious concerns associated with interrogation is the possibility of a false confession.

A person may confess to conduct they did not commit for a variety of reasons, including psychological pressure, exhaustion, fear, manipulation, desire to protect another person, misunderstanding, or belief that confessing will produce some immediate benefit.

The existence of a confession therefore does not automatically establish factual guilt.

From a legal perspective, courts may need to distinguish between:

• whether a confession was actually made;
• whether it was obtained during custodial interrogation;
• whether Miranda requirements were satisfied;
• whether the suspect validly waived applicable rights;
• whether the statement was voluntary;
• whether independent evidence corroborates the statement.

This illustrates why criminal procedure treats interrogation as a constitutional process rather than simply an investigative technique.

Police Interrogation and the Exclusionary Rule

When constitutional rules governing interrogation are violated, suppression may become an issue.

A defense may challenge a statement before trial and ask the court to prevent the prosecution from introducing the statement in its case.

The prosecution may then argue that:

• the person was not in custody;
• there was no interrogation;
• Miranda warnings were properly given;
• the suspect validly waived the rights;
• the statement was volunteered;
• the particular use of the statement is constitutionally permissible;
• an independent constitutional doctrine allows the evidence to be used.

The court must therefore identify the precise constitutional issue before determining the appropriate remedy.

A Practical Example

Consider a burglary investigation.

Police arrest Daniel based on probable cause and place him in a police vehicle. Before asking him questions about the burglary, officers give him Miranda warnings.

Daniel says that he understands his rights and agrees to speak.

An officer asks:

“Where were you between 10 p.m. and midnight?”

Daniel answers.

The officer then asks:

“Why did you take the jewelry?”

Daniel responds with an admission.

These are straightforward examples of custodial interrogation following Miranda warnings and an apparent waiver.

Now change the facts.

Daniel is arrested and placed in the vehicle. Without asking him anything, an officer begins ordinary conversation about the transportation process. Daniel suddenly says:

“I didn’t mean for anyone to get hurt.”

The legal question becomes whether that statement was volunteered or whether something the officer said or did constituted interrogation.

Now change the facts again.

After Daniel asks for an attorney, officers deliberately engage in conduct that they should know is reasonably likely to prompt him to explain what happened.

The analysis becomes substantially more difficult because Innis requires attention to the functional equivalent of express questioning.

These examples show why the words custody, interrogation, waiver, invocation, and voluntariness must be kept analytically separate.

A Framework for Analyzing Police Interrogation

When evaluating whether a police interrogation complied with constitutional requirements, the following sequence is useful.

1. Identify the setting

Where did the questioning occur?

Was it on the street, during a traffic stop, at a police station, in a police vehicle, at a person’s home, or in a detention facility?

2. Determine whether the person was in custody

Ask whether the circumstances imposed a restraint comparable to formal arrest or otherwise deprived the person of freedom in a constitutionally significant way.

3. Determine whether there was interrogation

Identify direct questions first.

Then consider whether police conduct constituted the functional equivalent of questioning because it was reasonably likely to elicit an incriminating response.

4. Determine whether Miranda was required

If the person was subjected to custodial interrogation, examine whether the required Miranda safeguards were provided.

5. Examine invocation and waiver

If Miranda rights were given, determine whether the suspect invoked a right or waived the applicable protections.

The details of invocation and waiver require careful analysis and should not be reduced to the question of whether a person simply “signed a form.”

6. Examine voluntariness

Even if Miranda requirements were satisfied, ask whether the statement was voluntarily made or resulted from unconstitutional coercion.

7. Identify the proposed use of the statement

Finally, determine how the prosecution seeks to use the statement.

The constitutional consequences can differ depending on whether the government seeks to introduce the statement in its case-in-chief, use it for impeachment, or rely on evidence derived from it.

Police Interrogation vs. Other Criminal Procedure Concepts

Concept	Central Question
Reasonable suspicion	Is there an objective basis for a temporary investigative detention?
Probable cause	Is there sufficient basis for an arrest or search under the applicable constitutional rule?
Custody	Is the person’s freedom restrained in a manner comparable to formal arrest?
Interrogation	Are police expressly questioning the person or engaging in its functional equivalent?
Miranda	Have the required safeguards been provided before custodial interrogation?
Waiver	Did the suspect knowingly, intelligently, and voluntarily relinquish applicable Miranda protections?
Voluntariness	Was the statement obtained without unconstitutional coercion?
Suppression	Should the court prevent the government from using the statement or other challenged evidence?

Keeping these concepts separate makes criminal-procedure analysis considerably clearer.

Federal and State Differences

The federal Constitution establishes a constitutional floor for police interrogation.

States must comply with applicable federal constitutional requirements, but they may provide additional protections through state constitutions, statutes, court rules, or judicial decisions.

State law may therefore impose requirements concerning matters such as:

• recording custodial interrogations;
• juvenile questioning;
• access to counsel;
• interrogation procedures;
• treatment of vulnerable suspects;
• admissibility of confessions;
• additional procedural safeguards.

Accordingly, a statement that satisfies the federal constitutional minimum is not necessarily admissible under every state’s law.

Why Police Interrogation Matters

Interrogation occupies a unique position in criminal procedure because it concerns evidence created by the interaction between government investigators and the person being investigated.

A physical object exists independently of police questioning. A statement does not. It is produced through communication, and the circumstances surrounding that communication can directly affect its reliability, voluntariness, and constitutional admissibility.

The law therefore attempts to balance two legitimate interests.

Police need effective investigative tools. At the same time, individuals must be protected against compelled self-incrimination and unconstitutional interrogation practices.

The result is not a categorical prohibition on police questioning. Instead, American criminal procedure establishes constitutional boundaries around when and how custodial questioning may occur.

Frequently Asked Questions

Is every police question an interrogation?

No. Police may ask questions during consensual encounters and other situations that do not constitute custodial interrogation. The constitutional meaning of interrogation becomes particularly important when a person is in custody.

Does being arrested automatically mean Miranda applies?

No. Miranda is concerned with custodial interrogation, not custody alone. A person can be arrested without being questioned.

Can police question someone before arrest without giving Miranda warnings?

Generally, Miranda does not apply merely because a person is being questioned before custody. However, the precise circumstances matter, and other constitutional rules—including voluntariness principles—can still apply.

Can police interrogate someone without asking a direct question?

Yes. Under Rhode Island v. Innis, interrogation can include the functional equivalent of express questioning when police words or actions are reasonably likely to elicit an incriminating response.

Is a spontaneous confession automatically inadmissible?

No. A genuinely volunteered statement is not automatically barred simply because the person was in custody. The question is whether police interrogation prompted the statement.

Is a Miranda violation the same as an involuntary confession?

No. A Miranda violation concerns the constitutional safeguards governing custodial interrogation. An involuntary confession involves unconstitutional coercion. The two issues can overlap but are legally distinct.

Can police lie during an interrogation?

Police interrogation techniques and deception raise complicated constitutional and state-law questions. The use of deception does not automatically resolve the constitutional analysis one way or the other. Courts examine the circumstances and, where relevant, whether the resulting statement was voluntary and constitutionally obtained.

Can a suspect have a lawyer present during interrogation?

Yes. The Miranda framework protects the right to have counsel present during custodial questioning, subject to the detailed rules governing invocation, waiver, and the separate Sixth Amendment right to counsel.

What happens when police violate Miranda?

A Miranda violation can result in restrictions on the government’s use of the resulting statement. The exact remedy depends on the nature of the violation and the proposed use of the evidence. It does not mean that every piece of evidence connected in some way to an interrogation is automatically excluded.

Conclusion

Police interrogation is a central part of criminal investigation, but it is not an area in which investigators have unlimited authority. The Constitution recognizes the government’s legitimate need to question suspects while imposing safeguards designed to protect individuals from compelled self-incrimination and unconstitutional interrogation.

The most important analytical distinction is between custody and interrogation. Custody concerns the person’s freedom. Interrogation concerns police conduct directed toward obtaining an incriminating response. When the two come together, the Miranda framework becomes central.

Understanding police interrogation therefore requires more than memorizing the phrase “you have the right to remain silent.” It requires understanding what counts as custody, what constitutes interrogation, what qualifies as its functional equivalent, how volunteered statements differ from elicited statements, how Miranda relates to the Fifth Amendment, how the Sixth Amendment fits into the picture, and how courts determine the consequences of constitutional violations.

Those distinctions provide the foundation for understanding the next major subjects in criminal procedure: Miranda Rights, invocation and waiver, the right to counsel during interrogation, and the admissibility of confessions and statements.
