FIFTH AMENDMENT - What is the significance of Miranda v. Arizona (1966)?

We've all heard the police on television shows say something like "you have the right to remain silent, anything you say or do may be used against you in a court of law" during an arrest. This statement is called the Miranda Warning. Police are required to repeat this before questioning the accused as part of the Fifth Amendment. The Miranda Warning reminds citizens that they don't have to testify against themselves.
