Many commentators have observed that when we speak of "the Warren Court," we mean the Warren Court that lasted from 1962 (when Arthur Goldberg replaced Felix Frankfurter) to 1969 (when Earl Warren retired). But when we speak of the Warren Court's "revolution" in American criminal procedure we mean the Warren Court that lasted from 1961 (when the landmark case of Mapp v. Ohio was decided) to 1966 or 1967. In its final years, the Warren Court was not the same Court that had handed down Mapp or Miranda v. Arizona.
