22.1 Confessions, Miranda & the Privilege Against Self-Incrimination

22.1 Confessions, Miranda & the Privilege Against Self-Incrimination

NCBE's outline tests confessions under three sources of law: due process (voluntariness), the Fifth Amendment privilege and Miranda, and the Sixth Amendment right to counsel. This section covers the first two and the privilege more generally; the Sixth Amendment is covered in Section 22.2, and double jeopardy in Section 23.2.

Fourteenth Amendment Voluntariness: The Due Process Standard

Independent of Miranda, the Due Process Clauses of the Fifth and Fourteenth Amendments demand that any confession introduced against a criminal defendant be voluntary (Spano v. New York).

• Totality of the Circumstances: Courts assess voluntariness by examining both the characteristics of the accused (age, education, mental health, intoxication) and the conditions of the interrogation (length of detention, continuous questioning, sleep/food deprivation, physical violence, or psychological isolation).
• Coercive Police Conduct Required (Colorado v. Connelly [1986]): Police coercion is a mandatory prerequisite to finding a confession involuntary. In Connelly, a mentally ill defendant approached a police officer and confessed to murder because he believed "the voice of God" commanded him to confess. The Supreme Court held that because police engaged in zero coercive overreaching, the confession was voluntary under the Due Process Clause.
• Consequences of Involuntariness: A coerced, involuntary confession is inadmissible for ALL purposes. It cannot be used in the prosecution's case-in-chief, nor can it be used to impeach the defendant's credibility at trial. Any physical fruits derived from an involuntary confession are excluded under the Fruit of the Poisonous Tree doctrine.

The Fifth Amendment Miranda Doctrine

In Miranda v. Arizona (1966), the Supreme Court established a prophylactic framework to dispel the inherently coercive pressures of custodial police interrogation. Before conducting a custodial interrogation, police must warn the suspect that: (1) they have the right to remain silent; (2) anything they say can and will be used against them in court; (3) they have the right to an attorney; and (4) if they cannot afford an attorney, one will be appointed.

1. The Two Triggers: Custody + Interrogation

Miranda warnings are required only when both custody and interrogation coincide. If either element is missing, un-Mirandized statements are fully admissible (provided they are voluntary).

Trigger 1: Custody

• Standard: Custody is determined by an objective test: would a reasonable person in the suspect's position believe they were deprived of their freedom of action to a degree associated with a formal arrest? (Berkemer v. McCarty).
• Non-Custodial Situations: Routine traffic stops and Terry street detentions are not custodial because they are brief, public, and non-coercive (Berkemer). Voluntary appearances at police stations for interviews where the suspect is told they are free to leave are not custodial (Oregon v. Mathiason).
• Incarcerated Inmates (Howes v. Fields [2012]): Imprisonment alone does not automatically create Miranda custody. When an inmate is questioned about outside events, custody exists only if additional restrictions are imposed beyond normal prison life.
• Undercover Agents (Illinois v. Perkins [1990]): Miranda warnings are not required when an incarcerated suspect speaks freely to an undercover officer posing as a fellow inmate, because there is no police-dominated coercive atmosphere.

Trigger 2: Interrogation

• Standard (Rhode Island v. Innis [1980]): Interrogation encompasses express questioning or its functional equivalent—any words or actions on the part of police (other than those normally attendant to arrest and custody) that police know or should know are reasonably likely to elicit an incriminating response.
• Spontaneous Statements: Volunteered, unprompted statements made without police solicitation are not the product of interrogation and are fully admissible.
• Routine Booking Exception (Pennsylvania v. Muniz [1990]): Police may ask routine biographical questions necessary to complete administrative booking (name, address, date of birth, age) without administering Miranda warnings.

2. The Public Safety Exception (New York v. Quarles [1984])

If police questioning is prompted by an objectively reasonable need to protect the police or the public from an immediate danger (e.g., locating an abandoned, loaded firearm discarded in a supermarket), Miranda warnings are excused. Both the suspect's unwarned statements and the recovered physical weapon are admissible in the prosecution's case-in-chief.

3. Invocation of Miranda Rights

To invoke Miranda protections, the suspect's statement must be clear, unambiguous, and unequivocal (Davis v. United States [1994]; Berghuis v. Thompkins [2010]). Remaining completely silent or uttering ambiguous statements (such as "Maybe I should talk to a lawyer") does not invoke Miranda.

The Edwards Bright-Line Bar (Edwards v. Arizona [1981]): Once an in-custody suspect unambiguously invokes the Fifth Amendment right to counsel, police cannot re-interrogate the suspect about the charged crime or any completely unrelated crime (Arizona v. Roberson), even with fresh warnings, unless counsel is present. Under Maryland v. Shatzer (2010), this protection expires only if the suspect is released from Miranda custody for at least 14 consecutive days.

4. Waiver of Miranda Rights

A suspect may waive Miranda rights provided the waiver is knowing, intelligent, and voluntary under the totality of circumstances.

• Implied Waiver (Berghuis v. Thompkins): A formal written or express oral waiver is not required. If police administer Miranda warnings, the suspect understands them, does not invoke rights, and eventually makes an uncoerced statement, the suspect has executed a valid implied waiver.

5. Exceptions to the Miranda Exclusionary Rule

• Impeachment Use (Harris v. New York [1971]): A statement taken in violation of Miranda (but otherwise voluntary) is excluded from the prosecution's case-in-chief, but MAY be introduced to impeach the defendant's credibility if the defendant takes the witness stand at trial.
• Physical Fruits Admissible (United States v. Patane [2004]): Failure to give Miranda warnings does not bar the admission of nontestimonial physical evidence (such as a gun or stolen loot) discovered as a result of a voluntary statement.
• Two-Step Questioning (Missouri v. Seibert [2004]): A deliberate police strategy to question a suspect without warnings, obtain a confession, administer warnings, and have the suspect repeat the confession renders the post-warning confession inadmissible unless curative steps (e.g., substantial break in time, explicit notice that first statement is unusable) were taken.

More on Confessions & the Privilege

Custody, Interrogation, Warnings, and Waiver

• Age and custody: A child's age, if known to the officer or objectively apparent, is relevant to whether a reasonable person would feel free to leave (J.D.B. v. North Carolina, 2011). An officer's undisclosed suspicions are not relevant (Stansbury v. California, 1994).
• Functional equivalent: Two officers' conversation in the front of a patrol car about the danger that a hidden shotgun posed to disabled children was not interrogation, because they had no reason to know that the suspect was particularly susceptible to such an appeal (Innis).
• Wording of warnings: Miranda warnings need not follow a precise script as long as they reasonably convey the suspect's rights (Duckworth v. Eagan, 1989; Florida v. Powell, 2010).
• Valid waiver despite limited information: A waiver is not invalid because police failed to tell the suspect that a lawyer was trying to reach him (Moran v. Burbine, 1986) or failed to list every crime they intended to ask about (Colorado v. Spring, 1987).
• Initiation: A suspect who asks, "Well, what is going to happen to me now?" initiates a generalized discussion about the investigation, allowing police to resume questioning after a valid waiver (Oregon v. Bradshaw, 1983).
• Invoking silence: A suspect must say that he wants to remain silent or does not want to talk; merely remaining silent for hours does not invoke the right (Berghuis v. Thompkins, 2010).

Two-Step Interrogations and Remedies

• Good-faith mistakes: If police obtain a voluntary but unwarned statement and later give proper warnings, a subsequent voluntary confession is admissible (Oregon v. Elstad, 1985).
• Deliberate strategy: If police deliberately question first, then warn, and then have the suspect repeat the confession, the warned statement is inadmissible unless curative measures—such as a substantial break in time and place or an explanation that the first statement is inadmissible—made the warnings effective (Missouri v. Seibert, 2004).
• Constitutional status: Miranda is a constitutional rule that Congress may not overrule by statute (Dickerson v. United States, 2000), but a violation of the Miranda rules alone does not support a civil damages claim under 42 U.S.C. § 1983 (Vega v. Tekoh, 2022).

Using a Defendant's Silence

The Privilege Against Self-Incrimination Generally

• Testimonial evidence only: The privilege protects against compelled communications, not physical evidence. Blood samples (Schmerber v. California, 1966), handwriting and voice exemplars, fingerprints, and appearing in a lineup are not protected. A drunk-driving suspect's slurred speech is physical evidence, but his inability to answer "What was the date of your sixth birthday?" is testimonial (Pennsylvania v. Muniz, 1990).
• Any proceeding: A witness may invoke the privilege in civil, administrative, legislative, and grand jury proceedings when an answer could tend to incriminate him in a criminal case. In a civil case, the factfinder may draw an adverse inference from a party's invocation (Baxter v. Palmigiano, 1976).
• Individuals only: Corporations and other collective entities have no privilege, and their custodians must produce entity records even if the contents incriminate them personally (Braswell v. United States, 1988).
• Documents: The contents of voluntarily prepared documents are not protected, but the act of producing documents can be testimonial when it concedes their existence, possession, or authenticity (Fisher v. United States, 1976; United States v. Hubbell, 2000).
• Immunity: The government may compel testimony by granting use and derivative-use immunity, which forbids using the testimony or evidence derived from it (Kastigar v. United States, 1972); transactional immunity is not required. Immunity granted by a state protects the witness against federal use as well (Murphy v. Waterfront Commission, 1964).
• Waiver by testifying: A defendant who testifies waives the privilege as to cross-examination on matters reasonably related to the direct testimony.
• Sentencing: A court may not draw an adverse inference from a defendant's silence at sentencing about the facts of the crime (Mitchell v. United States, 1999).
