Once the Court granted [certiorari in Dickerson] court-watchers knew the hour had come. At long last the Court would have to either repudiate Miranda, repudiate the prophylactic-rule cases [the cases viewing Miranda's requirements as not rights protected by the Constitution, but merely "prophylactic rules"] or offer some ingenious reconciliation of the two lines of precedent. The Supreme Court of the United States, however, doesn't "have to" do anything, as the decision in Dickerson once again reminds us.
