Which case established the requirement for Miranda warnings?

The case that established the requirement for Miranda warnings is indeed Miranda v. Arizona. This landmark Supreme Court decision from 1966 determined that individuals taken into police custody must be informed of their rights before being interrogated, specifically the right to remain silent and the right to legal counsel. The Court ruled that failure to provide these warnings could lead to any statements made during interrogation being deemed inadmissible in court.

The rationale behind this requirement is rooted in the Fifth Amendment, which protects individuals from self-incrimination. By ensuring that suspects are aware of their rights, the Miranda decision seeks to preserve the fundamental fairness of the legal process and to protect individuals from coercive interrogation practices. This case significantly impacted law enforcement procedures and the rights of the accused, solidifying the necessity for police to administer Miranda warnings during custodial interrogations.
