'See something, say something'
U.S. Army Reserve Sgt. 1st Class Brian Williams and his fiancée, Eileen Clemens, enjoy a game at Levi Stadium, Dec. 20, 2015. Crediting military training and vigilance, Williams reported a man acting suspiciously taking pictures of the stadium (home of Super Bowl 50) with what appeared to be a small camera and some sort of transmission device. Stadium authorities detained the man and confirmed Williams’ suspicions, stating the FBI and Homeland Security officials were holding the man for further questioning.
