That's the way it works. The NSA runs Echelon with Canada, Britain, Australia and New Zealand as a series of listening posts around the world that eavesdrop on terrorists, drug lords and hostile foreign governments. But to find out what the bad guys are up to, all electronic communications, including those of the good guys, must be captured and analyzed for key words by super computers. That is a fact that makes Frost uncomfortable, even though he believes the world needs intelligence gathering capabilities like Echelon. The computer spit that conversation out.
Democracies usually have laws against spying on citizens.
But Frost says Echelon members could ask another member to spy for them in an end run around those laws. For example, Frost tells Kroft that his Canadian intelligence boss spied on British government officials for Prime Minister Margaret Thatcher. The British Parliament now have total deniability. American politicians may also have been eavesdropped on, says Margaret Newsham, a woman who worked at Menwith Hill in England, the NSA's largest spy station. The exposing of such possible abuses of Echelon will surely add to the growing firestorm in Europe over the system.
