In the US, the requirement that police officers must inform a criminal suspect of his or her rights under law before or during being taken into custody or interrogated. These include the defendant’s (i) right to remain silent (ii) the knowledge that anything said by the defendant may be used as evidence in a court of law, (iii) that the defendant has a right to an attorney and (iv) if they cannot afford an attorney, an attorney will be provided to represent the defendant by the government and at no cost to the defendant (via a court appointed attorney.) This warning was created pursuant to the case of Miranda v. Arizona in 1966.
