Russell Tice, a longtime insider at the National Security Agency, is now a whistleblower the agency would like to keep quiet. For 20 years, Tice worked in the shadows. I specialized in what's called special access programs," Tice said of his job. "We called them 'black world' programs and operations." Some of those secret "black world" operations run by the NSA were operated in ways that he believes violated the law. He is prepared to tell Congress all he knows. Tice says the technology exists to track and sort through every domestic and international phone call...and to search for key words or phrases that a terrorist might use. Tice...says the number of Americans subject to eavesdropping by the NSA could be in the millions if the full range of secret NSA programs is used. "For most Americans [who] placed an overseas communication, more than likely they were sucked into that vacuum." He told ABC News that he was a source for the [New York] Times. But Tice maintains that his conscience is clear. "We need to clean up the intelligence community. We've had abuses, and they need to be addressed." The NSA revoked Tice's security clearance in May of last year based on what it called psychological concerns and later dismissed him. Tice calls that bunk and says that's the way the NSA deals with troublemakers and whistleblowers.
