5.3 Miranda Warnings & Custodial Interrogations

Key Takeaways

  • The Fifth Amendment protection against self-incrimination mandates Miranda warnings only when a suspect is subjected to both custody and interrogation (the 'dual trigger').
  • Custody is determined by an objective test: whether a reasonable person in the suspect's position would feel free to terminate the interview and leave; interrogation includes express questioning or its functional equivalent (Rhode Island v. Innis).
  • Under Edwards v. Arizona, an unambiguous invocation of the right to counsel requires immediate cessation of all questioning until an attorney is present, unless the suspect reinitiates communication.
  • Under Berghuis v. Thompkins, a suspect must unambiguously invoke the right to remain silent or to counsel; remaining silent does not by itself constitute an invocation.
  • In Pennsylvania, juvenile confessions are evaluated under the totality of circumstances (Commonwealth v. Williams), considering age, intelligence, experience, and opportunity to consult with an interested adult.

5.3 Miranda Warnings & Custodial Interrogations

Interrogations and suspect interviews are critical police functions. However, police officers must navigate complex constitutional safeguards when questioning individuals. The Fifth and Sixth Amendments of the U.S. Constitution, along with Article I, Section 9 of the Pennsylvania Constitution, strictly dictate when procedural warnings are required and how suspect rights must be honored. For Pennsylvania law enforcement officers, failure to adhere to these rules results in the complete suppression of incriminating admissions.


Fifth Amendment & Miranda v. Arizona

The Fifth Amendment guarantees that no person "shall be compelled in any criminal case to be a witness against himself." In Miranda v. Arizona, 384 U.S. 436 (1966), the U.S. Supreme Court established procedural safeguards to protect suspects from the inherently coercive atmosphere of custodial interrogation.

The Standard Miranda Warnings

Prior to custodial interrogation, officers must warn the suspect of the following four core rights:

  1. You have the right to remain silent.
  2. Anything you say can and will be used against you in a court of law.
  3. You have the right to talk to a lawyer and have a lawyer present with you while you are being questioned.
  4. If you cannot afford a lawyer, one will be appointed to represent you before any questioning if you wish.

The Dual Trigger for Miranda: Custody + Interrogation

Miranda warnings are not required every time a police officer talks to a citizen. Miranda is required only when two conditions exist simultaneously—commonly known as the Dual Trigger: Miranda Required=Custody+Interrogation\text{Miranda Required} = \text{Custody} + \text{Interrogation}

1. Custody Test

Custody is evaluated using an objective standard: Would a reasonable person in the suspect's position believe that their freedom of movement was restricted to a degree associated with a formal arrest?

  • Subjective Intent Irrelevant: Neither the officer's uncommunicated intent to arrest nor the suspect's subjective belief dictates custody.
  • Custody Factors: Location of interview (police station vs. public street), length of questioning, physical restraints (handcuffs), number of officers present, tone of voice, and whether the suspect was told they were free to leave.
  • Traffic Stops: Routine traffic stops (Berkemer v. McCarty) and field Terry stops generally do not constitute custody for Miranda purposes.

2. Interrogation Test

Interrogation includes express questioning or its functional equivalent under Rhode Island v. Innis, 446 U.S. 291 (1980):

  • Express Questioning: Direct interrogation aimed at eliciting information about a crime.
  • Functional Equivalent: Any words or actions on the part of the police (other than those normally attendant to arrest and custody) that officers should know are reasonably likely to elicit an incriminating response from the suspect.
  • Spontaneous Statements: Unsolicited, voluntary statements initiated by a suspect while in custody are not the product of interrogation and are admissible without Miranda warnings.

Fifth Amendment vs. Sixth Amendment Right to Counsel

Officers must distinguish between Fifth Amendment Miranda rights and Sixth Amendment right to counsel:

FeatureFifth Amendment Right to CounselSixth Amendment Right to Counsel
Constitutional Source5th Amendment (Self-Incrimination protection)6th Amendment (Assistance of Counsel)
Attaches When?During custodial interrogationAutomatically upon formal charging (filing complaint, arraignment)
Offense SpecificityNon-offense specific (applies to any crime)Offense specific (applies only to charged crime)
Waiver RuleSuspect can waive during interviewSuspect can waive, but police cannot initiate contact without notice after charging

Invocation of Rights: Edwards & Berghuis Standards

When a suspect is advised of their Miranda rights, they may choose to invoke their right to remain silent or their right to counsel.

Invocation Must Be Unambiguous (Berghuis v. Thompkins)

Under Berghuis v. Thompkins, 560 U.S. 370 (2010), a suspect must unambiguously and unequivocally invoke their rights. Merely remaining silent for hours during questioning does not invoke the right to remain silent. The suspect must state clearly: "I want to remain silent" or "I want an attorney."

Invocation of Right to Counsel (Edwards v. Arizona)

Under Edwards v. Arizona, 451 U.S. 477 (1981), if a suspect unambiguously requests an attorney, a strict bright-line rule applies:

  • Immediate Cessation: All interrogation must stop immediately.
  • No Re-Approach: Police cannot re-contact or re-interrogate the suspect about any offense while in custody, unless:
    1. The suspect's counsel is physically present, OR
    2. The suspect independently reinitiates communication with police.

Waiver of Miranda Rights

For a suspect's statements to be admissible after warnings, the prosecution must prove by a preponderance of evidence that the suspect waived their rights.

A valid waiver must meet three criteria:

  1. Knowing: The suspect understood their rights and the consequences of waiving them.
  2. Intelligent: The suspect had the mental capacity to comprehend the warnings.
  3. Voluntary: The waiver was the product of a free and deliberate choice, free from coercion, intimidation, or deception.

Best Practice: Officers should utilize a standard written Miranda Waiver Form signed by the suspect and witnessed by officers.


Special Protections for Juvenile Interrogations in PA

In Pennsylvania, questioning juvenile suspects requires heightened scrutiny to protect against coerced confessions.

Commonwealth v. Williams (1984) — Totality of Circumstances

Historically, Pennsylvania enforced a rigid "Interested Adult Rule" requiring an opportunity for a juvenile to consult with a parent or adult before waiving rights. In Commonwealth v. Williams, 504 Pa. 511 (1984), the PA Supreme Court adopted the Totality of the Circumstances standard for juvenile waivers:

  • Key Evaluation Factors:
    1. The juvenile's age, intelligence, education, and maturity.
    2. The juvenile's prior experience with law enforcement and the criminal justice system.
    3. Whether the juvenile was given the opportunity to consult with an interested, informed adult (parent, guardian, attorney).
    4. The duration, location, and conditions of the detention and questioning.

While the absence of an interested adult does not automatically invalidate a juvenile's waiver in PA, courts examine adult presence as a heavy factor in determining whether the waiver was knowing and voluntary.

Key Takeaways for Act 120 Candidates

  • Miranda warnings require BOTH custody AND interrogation.
  • Custody is judged objectively based on whether a reasonable person would feel free to leave.
  • Edwards Rule: Request for an attorney shuts down interrogation completely until counsel is present.
  • Berghuis Rule: Invocations of silence or counsel must be clear and spoken out loud.
  • Juvenile confessions in PA are judged under totality of circumstances (Commonwealth v. Williams).
