Today marks the 47th anniversary of the day that the U.S. Supreme Court handed down the decision in the case Miranda v. Arizona. The landmark decision established the requirement that police officers must advise suspects they are arresting of their rights before they are interrogated. The Miranda rights, as they are often called, have become familiar to anyone who has watched movies or television shows in the last 47 years. The case originated from the arrest of Ernesto Miranda in Phoenix, Arizona for rape in 1963 and eventually made its way to the U.S. Supreme Court.
