What is the test for waiving the Miranda rights?

We turn first to the issue of waiver. The Fifth Amendment to the United States Constitution guarantees that a suspect in a criminal case "may not be compelled to be a witness against himself in any respect." (Colorado v. Spring (1987) 479 U.S. 564, 574.) "To protect the Fifth Amendment privilege against self-incrimination, a person undergoing a custodial interrogation must first be advised of his right to remain silent, to the presence of counsel, and to appointed counsel, if indigent. [Citation.] As long as the suspect knowingly and intelligently waives these rights, the police are free to interrogate him. [Citation.]" (People v. Stitely (2005) 35 Cal.4th 514, 535.) The waiver inquiry has two aspects. "First, the relinquishment of the right must have been voluntary in the sense that it was the product of a free and deliberate choice rather than intimidation, coercion, or deception. Second, the waiver must have been made with a full awareness of both the nature of the right being abandoned and the consequences of the decision to abandon it. Only if the 'totality of the circumstances surrounding the interrogation' reveals both an uncoerced choice and the requisite level of comprehension may a court properly conclude that the Miranda rights have been waived. [Citations.]" (Moran v. Burbine (1986) 475 U.S. 412, 421.)
