Miranda v. Arizona: More Than Just Your Rights

Everyone knows “You have the right to remain silent...” But Miranda v. Arizona is about much more than the warnings themselves. The case addressed a fundamental question: How do we protect the Fifth Amendment privilege against self-incrimination during police interrogation?

Before Miranda, confessions obtained through coercive interrogation techniques were challenged case-by-case under a “voluntariness” test. This was unpredictable and failed to prevent abuses. The Court found that the inherently coercive nature of custodial interrogation — isolation, psychological pressure, unfamiliarity with legal rights — required a prophylactic rule to protect suspects.

The Court held that before custodial interrogation, law enforcement must inform the suspect of four things:

1. The right to remain silent
2. That anything said can be used against them in court
3. The right to an attorney
4. That an attorney will be appointed if they cannot afford one

If these warnings are not given, any statements obtained are inadmissible in the prosecution's case-in-chief.

Custody + Interrogation: Miranda only applies when both are present. A traffic stop is not custody. A casual conversation is not interrogation.

Waiver: Suspects can waive their Miranda rights, but the waiver must be knowing, voluntary, and intelligent.

Public safety exception: Officers can ask questions necessary to protect public safety without Miranda warnings (New York v. Quarles).

Fruit of the poisonous tree: Physical evidence discovered as a result of un-Mirandized statements may still be admissible (United States v. Patane).
