Miranda v. Arizona reshaped modern interrogation by recognizing that custodial questioning creates psychological pressure that can compel statements. The Supreme Court held that the Fifth Amendment requires suspects to be advised of their right to remain silent and to an attorney before custodial interrogation. These protections safeguard voluntary statements, reduce coercion, and preserve the integrity and reliability of evidence obtained during interviews.

Brown v. Mississippi marked a turning point: confessions obtained through brutal interrogation violate due process and are inadmissible.
