What requirement was established by the Miranda vs. Arizona ruling?

The requirement established by the Miranda vs. Arizona ruling is that the accused must be notified of their rights before questioning. This landmark decision, made by the U.S. Supreme Court in 1966, mandated that individuals taken into police custody must be informed of their rights to silence and legal counsel. The ruling aimed to protect the Fifth Amendment rights against self-incrimination and ensure that any statements made during interrogation are voluntary and not coerced. This requirement is crucial for ensuring that suspects are aware of their legal protections, which helps maintain the integrity of the justice system and safeguard against abuses during police interrogations.
