Which legal principle requires police to inform a person of their rights when taken into custody?

The principle that mandates police to inform an individual of their rights when taken into custody is known as Miranda rights. This requirement arose from the U.S. Supreme Court case Miranda v. Arizona in 1966, which established that individuals have the right to be aware of their rights to remain silent and to have an attorney present during questioning. The purpose of this requirement is to protect individuals against self-incrimination and ensure that they understand their rights when facing potential legal proceedings.

In contrast, the exclusionary rule addresses the admissibility of evidence obtained illegally or in violation of constitutional rights, while self-defense pertains to legal justification for using force in defense of oneself. Probable cause refers to the legal standard that law enforcement must meet before making an arrest or conducting a search. Thus, while all these principles play significant roles in law enforcement and legal proceedings, Miranda rights specifically focus on informing individuals of their rights during custodial interrogation.
