This 24 year veteran of the FBI reveals the origins of NSA's massive surveillance program which was brought again to public awareness by Edward Snowden. The program was first proposed publicly by the infamous John Poindexter and was "supposedly squelched by the American people" in 2003. She reports on many of the details associated with NSA and many other government agencies, and the dangers of such surveillance for American citizens.
