Total tyranny ..

“The National Security Agency’s capability at any time could be turned around on the American people, and no American would have any privacy left, such is the capability to monitor everything: telephone conversations, telegrams, it doesn’t matter. There would be no place to hide. If a dictator ever took over, the N.S.A. could enable it to impose total tyranny, and there would be no way to fight back.”—Senator Frank Church (1975).
