On June 13, 1966, the United States Supreme Court delivered its decision in Miranda v. Arizona, establishing the Miranda rights. This landmark ruling required police to inform suspects of their rights to an attorney and against self-incrimination before questioning them. This decision was a critical development in U.S. law enforcement and civil liberties, aiming to protect suspects from involuntary confessions and coercive police practices, and has since become a fundamental part of the criminal arrest process and popular culture in the United States.
