In 1963, Ernesto Miranda was arrested for kidnapping and rape. Miranda made a confession without previously being told of his constitutional right to remain silent and his right to have an attorney present during police questioning.
At his trial, he was convicted based only on his confession. The Supreme Court ruled that Miranda was intimidated by the interrogation and that he did not understand his right not to incriminate himself or his right to counsel. On this basis, his conviction was overturned. Miranda was later convicted in a new trial, this time with witnesses testifying against him, as well as other evidence. He served eleven years in prison.
Ironically, when Ernesto Miranda was later killed in a knife fight, his murderer was read the Miranda rights, which he invoked, declining to give a statement.
This has been a moment of ... WTF?!
