Hundreds of US citizens overseas have been eavesdropped on as they called friends and family back home, according to two former military intercept operators who worked at the giant National Security Agency (NSA) center in Fort Gordon, Georgia. These were just really everyday, average, ordinary Americans who happened to be in the Middle East, in our area of intercept and happened to be making these phone calls on satellite phones," said Adrienne Kinne, a 31-year old US Army Reserves Arab linguist assigned to a special military program at the NSA's Back Hall at Fort Gordon from November 2001 to 2003. She said US military officers, American journalists and American aid workers were routinely intercepted and "collected on" as they called their offices or homes in the United States. Another intercept operator, former Navy Arab linguist, David Murfee Faulk, 39, said he and his fellow intercept operators listened into hundreds of Americans picked up using phones in Baghdad's Green Zone from late 2003 to November 2007. Both former intercept operators came forward at first to speak with investigative journalist [James] Bamford for a book on the NSA, The Shadow Factory, to be published next week. "It's extremely rare," said Bamford, who has written two previous books on the NSA, including the landmark Puzzle Palace which first revealed the existence of the super secret spy agency. "Both of them felt that what they were doing was illegal and improper, and immoral, and it shouldn't be done, and that's what forces whistleblowers."
