Miranda v. Arizona (1966)
A series of casing, the one it is named after involving a man arrested for robbery, positively identified, being interrogated for 2 hours without being aware of his rights, and confessing to murder. The question was does police interrogation of individuals without informing them of their rights violate the 5th? The Supreme Court decided yes and laid down procedural safeguards and required rights to be read, now known as the Miranda Rights. It was said that "the blood of the accused is not the only hallmark of an unconstitutional inquisition."
