"Guardian" reporter Glenn Greenwald on weekends on "All Things Considered"
The Guardian newspaper has identified the source for a series of reports it's published in recent days on secret U.S. surveillance activity as a former technical assistant for the CIA who now works for a private-sector defense and technology consulting firm.
Gen. Michael Hayden, a former director of the National Security Agency, tells NPR's Weekend Edition Sunday that the government's acquisition of phone records and surveillance of Internet activity is lawful and justified by the changing nature of the war on terrorism.
Hayden, who served as NSA chief from 1999-2005 and is also a former CIA director, says NSA's activities are "perfectly legal" and "an accurate reflection of balancing our security and our privacy."
Investigators were reportedly looking into family connections in their search for a motive in Friday's shooting rampage in Santa Monica, Calif., that left six people dead, including the gunman and a woman who died Sunday from injuries sustained in the assault.
