What pivotal change in criminal procedure resulted from Miranda v. Arizona?

The pivotal change in criminal procedure that emerged from Miranda v. Arizona is the establishment of required interrogational protocols. This landmark Supreme Court case set forth the requirement that individuals taken into police custody must be informed of their rights prior to being subjected to interrogation. Specifically, this includes the right to remain silent and the right to have an attorney present during questioning. This decision aimed to protect the Fifth Amendment right against self-incrimination and ensure that defendants are aware of their legal rights, promoting a fairer judicial process.

The ruling highlighted the importance of safeguarding individuals from coercive interrogation practices that could lead to false confessions. As a result, police are now mandated to provide what are commonly referred to as "Miranda warnings" before engaging in any questioning, fundamentally transforming how law enforcement conducts interrogations and how rights are upheld in the criminal justice system.
