Which case set the guidelines for custodial interrogations in 1966?

The case that set the guidelines for custodial interrogations in 1966 is Miranda v. Arizona. This landmark Supreme Court decision established the requirement for law enforcement to inform individuals of their rights before conducting a custodial interrogation. These rights, often referred to as "Miranda rights," include the right to remain silent and the right to an attorney. The Court aimed to protect the Fifth Amendment right against self-incrimination and ensure that individuals are aware of their rights when being questioned by police.

Prior to this ruling, many individuals were not adequately informed of their rights, leading to potential coercion and false confessions. Miranda v. Arizona recognized that the environment of custodial interrogation is inherently intimidating, and thus requires that individuals be made aware of their legal protections to ensure fair treatment under the law. This case fundamentally influenced police procedures and the rights of suspects in the United States, reinforcing the importance of informed consent in legal settings.
