What is the state of the law in the context of the Miranda rights?

After Miranda, however, no fine distinction can be made as to the officer's intention when a suspect is subjected to express questioning. As stated in Rhode Island v. Innis, supra, 446 U.S. at page 301, 100 S.Ct. at page 1690, "... Miranda safeguards were designed to vest a suspect in custody with an added measure of protection against coercive police practices, without regard to objective proof of the underlying intent of the police." Under the dictates of Miranda, the officer's question in [690 P.2d 679] Sanchez--"Why did you do it?" would have resulted in an inadmissible statement.
