19. Miranda v Arizona  In 1963, Ernesto Miranda, a 23 year old mentally disturbed man, was accused of kidnapping and raping an 18-year-old woman in Phoenix, Arizona.  He was brought in for questioning, and confessed to the crime. He was not told that he did not have to speak or that he could have a lawyer present.  At trial, Miranda's lawyer tried to get the confession thrown out, but the motion was denied.  The case went to the Supreme Court in 1966.  The Court ruled that the statements made to the police could not be used as evidence, since Mr. Miranda had not been advised of his rights.
