No Place to Hide: Edward Snowden, the NSA, and the U.S. Surveillance State

by Glenn Greenwald

The United States government has perfected a technological capability that enables us to monitor the messages that go through the air.… That 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. —Senator Frank Church, Chair, Senate Select Committee to Study Governmental Operations with Respect to Intelligence Activities, 1975
