What 1966 Supreme Court case established that police must inform suspects of their rights before questioning?

The 1966 Supreme Court case that fundamentally altered police procedures during interrogations is known as Miranda v. Arizona. This landmark decision established that law enforcement must inform individuals of their constitutional rights before questioning them while in custody. Failure to do so renders any statements made by the suspect inadmissible as evidence in court.

The case originated from the arrest of Ernesto Miranda in 1963, who was accused of kidnapping and rape. Following a two-hour interrogation, Miranda signed a confession without ever being told of his right to remain silent or his right to an attorney. His confession was used to convict him, but the Supreme Court later overturned this conviction, recognizing that his Fifth Amendment right against self-incrimination and Sixth Amendment right to counsel had been violated.

The ruling, delivered by Chief Justice Earl Warren, highlighted the inherent pressure of custodial interrogations and the need for safeguards to protect a suspect's rights. The Court mandated that suspects be explicitly warned that they have the right to remain silent, that anything they say can be used against them in court, that they have the right to an attorney, and that if they cannot afford one, an attorney will be provided for them. These "Miranda warnings" quickly became a routine part of police procedure across the United States.

Miranda v. Arizona has profoundly impacted the criminal justice system, ensuring that confessions are obtained fairly and voluntarily. While initially controversial, the requirement to inform suspects of their rights has become deeply embedded in American legal culture, familiar to almost everyone through its frequent portrayal in popular media. This crucial decision continues to serve as a cornerstone for protecting individual liberties during police questioning.
