“Get Up, Stand Up… Stand Up For Your Right”
The Miranda warning (also referred to as Miranda rights) is a warning given by police in the United States to criminal suspects in police custody (or in a custodial interrogation) before they are interrogated to preserve the admissibility of their statements against them in criminal proceedings. In other words, a Miranda warning is a prophylactic criminal procedure rule that law enforcement is required to administer in order to protect an individual who is in custody and subject to direct questioning or its functional equivalent from a violation of his or her Fifth Amendment right against compelled self-incrimination. In Miranda v. Arizona, the Supreme Court held that the admission of elicited incriminating statement by a suspect not informed of these rights violates the Fifth Amendment privilege against self-incrimination and the Sixth Amendment right to counsel. Thus, if law enforcement officials decline to offer a Miranda warning to an individual in their custody, they may still interrogate that person and act upon the knowledge gained, but may not use that person’s statements to incriminate him or her in a criminal trial.
In Berghuis v. Thompkins, the Court held that, if a suspect waives this right and interrogation begins, the right to halt further interrogation by the police must be exercised explicitly, by revoking the prior waiver.
