Murrah Federal Building in Oklahoma City. On Thursday, July 31, 2014, the FBI capped off its attempt to persuade a federal judge in Salt Lake City that it is not hiding unreleased surveillance videos from the 1995 Oklahoma City bombing by bringing witnesses who testified that there has never been any security-camera videos of the bomb going off.
