Public disclosures (1972–2000)
In 1972, former NSA analyst Perry Fellwock under pseudonym Winslow Peck, first blew the whistle on ECHELON to Ramparts in 1972,[12] where he gave commentary revealing a global network of listening posts and his experiences working there. Fellwock also included revelations such as the Israeli attack on USS Liberty was deliberate and known by both sides, the existence of nuclear weapons in Israel in 1972, the widespread involvement of CIA and NSA personnel in drugs and human smuggling, and CIA operatives leading Nationalist China (Taiwan) commandos in burning villages inside PRC borders.[13]
In 1982, James Bamford, investigative journalist and author wrote The Puzzle Palace, an in-depth look inside the workings of the NSA, then a super-secret agency, and the massive eavesdropping operation under the codename "SHAMROCK". The NSA has used many codenames, and SHAMROCK was the codename used for ECHELON prior to 1975.[14][15]
