when are police required to administer the miranda warnings
Miranda warning The duty to warn only arises when police officers conduct custodial interrogations. The Constitution does not require that a defendant be advised of the Miranda rights as part of the arrest procedure, or once an officer has probable cause to arrest, or if the defendant has become a suspect of the focus of an investigation. Custody and interrogation are the events that trigger the duty to warn.
Miranda v. Arizona Miranda v. Arizona, 384 U.S. 436 (1966), was a landmark decision of the United States Supreme Court. In a 5â€“4 majority, the Court held that both inculpatory and exculpatory statements made in response to interrogation by a defendant in police custody will be admissible at trial only if the prosecution can show that the defendant was informed of the right to consult with an attorney before and during questioning and of the right against self-incrimination before police questioning, and that the defendant not only understood these rights, but voluntarily waived them.
