19 Oct Perry Fellwock
The existence the NSA was revealed to the public in 1971 by NSA analyst turned whistleblower Perry Fellwock. He was motivated by CIA whistleblower Daniel Ellsberg’s release of the Pentagon Papers. Fellwock published the details of ECHELON, the Five Eyes (FVEY) signals intelligence analysis network – NSA spying capabilities – ostensibly created to monitor the military and diplomatic communications of the Soviet Union and its Eastern Bloc allies during the Cold War in the early 1960s.
Because of the Fellwock revelations NSA spying on American citizens was suspended by the 1973 Church Committee. Digital-age successors to Perry Fellwock: Drake, Binney, Wiebe and Loomis. Research these geezers. Worth noting that the Edward Snowden revelations of NSA spying almost 40 years later did not result in legislative pushback against the security state apparatus.
