"Responses to the Government's Defense of National Security Agency Warrantless Wiretaps"
"In fact, the Supreme Court has never upheld warrantless wiretapping within the United States, for any purpose. In the landmark ruling of Katz v. United States (1967), the Supreme Court held that the Fourth Amendment applied to telephone calls, and that probable cause and a warrant are required before electronic surveillance of such communications may be conducted. And in a previously cited decision (United States v. United States District Court, 1972), the Supreme Court specifically rejected the argument that domestic security concerns justify warrantless wiretapping."
