What requirement was established by the case Miranda v. Arizona?

The case of Miranda v. Arizona established the requirement that defendants have the right to remain silent and to be informed of their rights before any interrogation by law enforcement. This ruling arose from concerns about the protection of individual rights against coercive interrogation practices. The Supreme Court determined that it is essential for individuals in custody to be made aware of their Fifth Amendment rights, which protects them against self-incrimination. This is crucial because without being informed of these rights, individuals may unknowingly waive them and give up their right to remain silent, potentially leading to involuntary confessions. The outcome of this case resulted in the well-known "Miranda Rights," which police are required to recite to suspects upon arrest, thereby defining a key aspect of due process in the American legal system.
