Miranda Rights
Ernesto Miranda, the defendant who took an appeal all the way to the United States Supreme Court after his arrest was ultimately convicted of the same crime at his second trial. Furthermore he was ultimately murdered at a bar following his release from prison. When advised of his right to remain silent, his killer exercised his right to refrain from incriminating himself thanks to the very protections that his victim was responsible for establishing.
