FILE - This March 19, 1975 file photo shows the Hughes Glomar Explorer, a 618-foot-long salvage ship built by the eccentric industrialist Howard Hughes, at the Long Beach harbor dock in Los Angeles, Calif. A Cold War-era legal tactic to conceal information, named the Glomar doctrine after the ship, was coined when the CIA said it would "neither confirm nor deny" whether records existed on a 1970's mission that used the Hughes Glomar Explorer to retrieve a portion of a Soviet submarine that had sunk in the Pacific Ocean. Now New York's highest court will consider whether the New York Police Department can use the Glomar doctrine to conceal information about whether it put Muslims under surveillance. (AP Photo, File)
