December 29, 2005 Project SHAMROCK...was an espionage exercise that involved the accumulation of all telegraphic data entering into or exiting from the United States. The Armed Forces Security Agency (AFSA) and its successor NSA were given direct access to daily microfilm copies of all incoming, outgoing, and transiting telegraphs via the Western Union and its a**ociates RCA and ITT. Operation Shamrock lasted well into the 1960s when computerized operations (HARVEST) made it possible to search for keywords rather than read through all communications. Project SHAMROCK became so successful that in 1966 the NSA and CIA set up a front company in lower Manhattan (where the offices of the telegraph companies were located) under the codename LPMEDLEY. At the height of Project SHAMROCK, 150,000 messages a month were printed and an*lyzed by NSA agents. In May 1975 however, congressional critics began to investigate and expose the program. As a result, NSA director Lew Allen terminated it. The testimony of both the representatives from the cable companies and of director Allen at the hearings prompted Senate Intelligence Committee chairman Sen. Frank Church to conclude that Project SHAMROCK was "probably the largest government interception program affecting Americans ever undertaken."
A lot of people are trying to say that it's a different world today, and that eavesdropping on a ma**ive scale is not covered under the FISA statute, because it just wasn't possible or anticipated back then. That's a lie. Project Shamrock began in the 1950s, and ran for about twenty years. It too had a ma**ive program to eavesdrop on all international telegram communications, including communications to and from American citizens. It too was to counter a terrorist threat inside the United States. It too was secret, and illegal. It is exactly, by name, the sort of program that the FISA process was supposed to get under control.
