On June 13th 1966 Miranda v. Arizona, 384 U.S. 436, was a decision of the U.S. Supreme Court in which the Court ruled that law enforcement in the United States must warn a person of their constitutional rights before interrogating them, or else the person's statements or confession cannot be used as evidence at their trial. Specifically, the Court held that under the Fifth Amendment to the U.S. Constitution, the government cannot use a person's statements made in response to an interrogation while in police custody as evidence at the person's criminal trial unless they can show that the person was informed of the right to consult with a lawyer before and during questioning, and of the right against self-incrimination before police questioning, and that the defendant not only understood these rights but also voluntarily waived them before answering questions.
Ernesto Arturo Miranda (March 9, 1941 – January 31, 1976) was an American laborer whose criminal conviction was set aside in the landmark U.S. Supreme Court case Miranda v. Arizona, which ruled that criminal suspects must be informed of their right against self-incrimination and their right to consult with an attorney before being questioned by police. This warning is known as a Miranda warning. Ernesto Miranda had been convicted of kidnapping, rape, and armed robbery charges based on his confession under police interrogation. Wikipedia.
