James Francis Rock v. Maryland

This case is another example of one in which the conviction must be set aside because the prosecution did not meet its burden of establishing that procedures were followed by the police which assure that an individual is accorded his privilege under the Fifth Amendment to the Constitution of the United States not to be compelled to incriminate himself. The necessary procedures were spelled out with specificity in Miranda v. State of Arizona, 384 U.S. 436, decided 13 June 1966, and are applicable to all cases the trial of which begin after that date. Johnson v. State of New Jersey, 384 U.S. 719, 721.1 We have discussed and interpreted Miranda and applied its holding in a number of cases decided heretofore.
