Any judicial reversal of the Mapp rule threatens to have just the opposite effect. Law enforcement officials are likely to treat a decision that illegally obtained evidence may be admitted into state criminal trials as though that were a practical suspension of the constitutional rules as to lawful arrest, search, and seizure. They are likely to feel that once again "the judiciary is okaying it." With the smell of revelations of FBI "black-bag jobs" and intelligence agency abuses still in the air, is this how we want the Court to contribute to the atmosphere of police practices as we enter our third century as a nation?
