Pentagon officials say they’re investigating students at the Army’s West Point Academy and the U.S. Naval Academy after they were filmed flashing “white power” hand gestures at the Army-Navy football game in Philadelphia on Saturday. Army cadets and Navy midshipmen in the stands were seen repeatedly making the signs, which resemble an “OK” gesture, and one such incident was broadcast live by ESPN. Last year the U.S. Coast Guard reprimanded an officer who used a similar hate symbol during a TV broadcast.
