The Core Miranda Rule

The Core Miranda Rule

The holding in Miranda v. Arizona is built as an exclusionary rule with a condition attached.¹ Police remain free to question people in custody, and the rule governs what the prosecution may do with the answers. The prosecution may not use statements stemming from custodial interrogation unless it demonstrates the use of procedural safeguards effective to secure the privilege against self-incrimination.² That sentence gives the prosecution both the act of using the statement and the burden of showing the safeguards. The burden sits there because the prosecution is the party offering the statement and the officers who took it are its witnesses, so the showing falls on the side best placed to supply it. A court deciding admissibility therefore asks first whether the prosecution can prove the safeguards were supplied. The exclusion also has a defined reach: it bars the prosecution from using the statement in its case in chief, and a statement excluded for want of the safeguards may still be used to impeach a defendant who takes the stand and contradicts it.³

The Court shaped the rule around the setting of custodial questioning because of what the cases before it showed. In each of the four consolidated cases, police officers, detectives, or a prosecutor questioned the defendant in a room that cut him off from the outside world, and none received a full and effective warning at the outset.⁴ Miranda himself was arrested for rape and kidnapping, booked into a Phoenix jail, and interrogated at length until he confessed, and the Court held that the confession should not have been admitted.⁵ Out of that record came a presumption: a statement taken from custodial interrogation is treated as compelled unless the safeguards dispel the pressure of the setting.⁶ A presumption works well here because it replaces a question no one can answer afterward, how much pressure a private room exerted, with questions a court can answer from the record, namely whether warnings were given and whether the suspect then waived. The constitutional anchor remains the Fifth Amendment guarantee that no person shall be compelled in any criminal case to be a witness against himself, and the safeguards are the means the Court chose to keep that guarantee alive in the station house.⁷

The safeguards supply the second half of the condition. Unless other fully effective means are devised, the suspect must be warned before any questioning of four things: the right to remain silent, that anything said may be used as evidence, the right to an attorney, and the right to an appointed attorney if the suspect cannot afford one.⁸ The qualifier that these measures are required only absent other fully effective means makes the warnings the required default and leaves open whether some other device could do the same work, a question the next section takes up.⁹ Once warned, the suspect may waive the rights and talk, but only if the waiver is made voluntarily, knowingly, and intelligently.¹⁰ The two steps do different work. The warnings supply information, because a suspect cannot choose to refuse without knowing that refusal is available, and the waiver supplies the choice, because a suspect who was merely told the rights has not yet decided anything. The protection also continues into the interview itself: if the suspect indicates in any manner and at any stage that a lawyer is wanted before speaking, there can be no questioning, a suspect who is alone and indicates a wish not to be interrogated may not be questioned, and having answered some questions does not take away the right to stop.¹¹ The rule thus has five working parts, which are custody, interrogation, warnings, waiver, and invocation, and each is taken up in its own section of this chapter.

The arrest, the room, and the questioning are identical to the facts that produced an excluded confession in Miranda. Only the supply of the safeguards changed, and that change is what separates an excluded statement from an admissible one.

The bar reaches every statement that stems from custodial interrogation, because the Court refused to distinguish between inculpatory statements and those alleged to be merely exculpatory.¹² The reason is practical. Whether an answer helps or hurts the accused is often visible only after the rest of the evidence comes in, and if the rule protected only answers that looked damaging when given, officers would have every reason to keep a suspect talking, since any answer could be turned into evidence once other proof arrived.

Two conditions must both be present before the bar applies. The statement must come from custody, meaning the person has been taken into custody or otherwise deprived of freedom of action in any significant way, and from interrogation, which the Court described as questioning initiated by law enforcement officers.¹³ Both are required because the safeguards answer a specific problem, the compelling atmosphere of in-custody questioning, and when either element is missing there is nothing for warnings to dispel. The Court said as much about general on-the-scene questioning as to the facts surrounding a crime, which its holding does not affect because that atmosphere is not necessarily present.¹⁴ Volunteered statements fall outside the rule for the same reason: police need not stop a person who walks into a station and says he wishes to confess, and volunteered statements of any kind are not barred by the Fifth Amendment.¹⁵ The sections on custody and on interrogation develop how each trigger is measured.

Compliance with the Miranda condition answers one question and leaves another open. Due process separately forbids the use of a confession procured by coercion, a court measures that by the totality of the circumstances, including the police conduct, the surrounding setting, and the characteristics of the defendant, and some government overreaching is required.¹⁶ The two inquiries can come out differently. A statement obtained without warnings can be voluntary in fact and still be excluded for want of the safeguards, and a statement obtained after full warnings and a signed waiver can still be excluded if police overreaching made it involuntary.¹⁷ Students lose points on this issue when they treat a completed warning and waiver as the end of the inquiry.
