Katz v. United States (389 U.S. 347)/Concurrence Douglas
Mr. Justice DOUGLAS, with whom Mr. Justice BRENNAN joins, concurring.
While I join the opinion of the Court, I feel compelled to reply to the separate concurring opinion of my Brother WHITE, which I view as a wholly unwarranted green light for the Executive Branch to resort to electronic eavesdropping without a warrant in cases which the Executive Branch itself labels 'national security' matters.
Neither the President nor the Attorney General is a magistrate. In matters where they believe national security may be involved they are not detached, disinterested, and neutral as a court or magistrate must be. Under the separation of powers created by the Constitution, the Executive Branch is not supposed to be neutral and disinterested. Rather it should vigorously investigate and prevent breaches of national security and prosecute those who violate the pertinent federal laws. The President and Attorney General are properly interested parties, cast in the role of adversary, in national security cases. They may even be the intended victims of subversive action. Since spies and saboteurs are as entitled to the protection of the Fourth Amendment as suspected gamblers like petitioner, I cannot agree that where spies and saboteurs are involved adequate protection of Fourth Amendment rights is assured when the President and Attorney General assume both the position of adversary-and-prosecutor and disinterested, neutral magistrate.
There is, so far as I understand constitutional history, no distinction under the Fourth Amendment between types of crimes. Article III, § 3, gives 'treason' a very narrow definition and puts restrictions on its proof. But the Fourth Amendment draws no lines between various substantive offenses. The arrests on cases of 'hot pursuit' and the arrests on visible or other evidence of probable cause cut across the board and are not peculiar to any kind of crime.
I would respect the present lines of distinction and not improvise because a particular crime seems particularly heinous. When the Framers took that step, as they did with treason, the worst crime of all, they made their purpose manifest.
