You have the right to remain silent

In the United States, the Miranda warning or famously "You have the right to remain silent" is a type of notification customarily given by police to criminal suspects in police custody (or in a custodial interrogation) advising them of their right to silence and, in effect, protection from self-incrimination; that is, their right to refuse to answer questions or provide information to law enforcement or other officials. These rights are often referred to as Miranda rights. The purpose of such notification is to preserve the admissibility of their statements made during custodial interrogation in later criminal proceedings. The Miranda warning is part of a preventive criminal procedure rule that law enforcement are required to administer to protect an individual who is in custody and subject to direct questioning or its functional equivalent from a violation of their Fifth Amendment right against compelled self-incrimination. In Miranda v. Arizona, the Supreme Court held that the admission of an elicited incriminating statement by a suspect not informed of these rights violates the Fifth Amendment and the Sixth Amendment right to counsel, through the incorporation of these rights into state law. Thus, if law enforcement officials decline to offer a Miranda warning to an individual in their custody, they may interrogate that person and act upon the knowledge gained, but may not ordinarily use that person's statements as evidence against them in a criminal trial.
