As a result of the miranda decision, police must now

As a result of the Miranda decision, police must now give the Miranda Warning to their suspects before interrogating them.

Explanation:

The Miranda warning is a communication that police officers in the United States must make to any person who has been arrested.

It was established after the Supreme Court of the United States ruled in the case Miranda v. Arizona of 1966, that the defendant Miranda's confession made to the police, was not admissible as evidence, because he had not been duly informed that he had the right to remain silent and to have the assistance of a lawyer and that any statement from him could be used as evidence against him. The criterion was ratified by the Supreme Court in the case Dickerson of 2000. The Miranda Warning has been established as a routine police procedure to avoid the violation of the constitutional right of not to incriminate oneself, guaranteed by the Fifth Amendment to the Constitution (right to remain silent).
