In the latest revelations about the National Security Agency, The Washington Post reports that the agency “has built a surveillance system capable of recording ‘100 percent’ of a foreign country’s telephone calls, enabling the agency to rewind and review conversations as long as a month after they take place.” The Post won’t say which nation, but it’s almost irrelevant – the NSA is able to do this, began it in 2009, and may soon expand the program, called MYSTIC, into other countries. “Analysts listen to only a fraction of 1 percent of the calls, but the absolute numbers are high,” notes the Post. “Each month, they send millions of voice clippings, or ‘cuts,’ for processing and long-term storage.”
