Lore & Background
After two hours of interrogation, Miranda signed a confession on a form stating it was voluntary, but he was never told of his right to counsel or his right to remain silent. At trial, his court-appointed lawyer Alvin Moore objected to the confession's admission, but the objection was overruled, and Miranda was convicted and sentenced to 20–30 years. The Arizona Supreme Court affirmed, emphasizing that Miranda had not specifically requested an attorney.
Reader's Guide
Miranda v. Arizona is significant because it fundamentally altered law enforcement procedures in the United States, making the Miranda warning a routine part of custodial interrogations. The Supreme Court held that under the Fifth Amendment, statements made during custodial interrogation are inadmissible unless the suspect is informed of the right to remain silent, that anything said can be used against them, and the right to an attorney—including one appointed if indigent—and voluntarily waives those rights. The decision was controversial, with dissenting justices warning it would hinder law enforcement and return criminals to the streets. Subsequent rulings, such as Berghuis v. The case remains a cornerstone of criminal procedure, balancing police interrogation practices with constitutional protections against self-incrimination.

Frequently Asked Questions
What are Miranda v. Arizona's powers/role?
Its core function is to require law enforcement to advise any person in custody of their Fifth Amendment right to remain silent and their Sixth Amendment right to counsel before conducting an interrogation. Without that advisement, any statements the suspect makes are generally inadmissible at trial.
Why is Miranda v. Arizona important?
It is one of the most cited precedents in U.S. criminal law because it created a concrete, enforceable safeguard for the privilege against self-incrimination. Every police officer in the country now recites a version of the warning before asking a suspect questions, making the case a daily part of American justice.
What was the vote and who wrote the opinion?
The Court split 5–4, with Chief Justice Earl Warren penning the majority opinion. The four dissenting justices argued the ruling went too far in dictating how police should conduct their investigations.
