ERRIE VIDEO Trump rally 7/13 Butler PA hours before President Trump SHOT

This video was taken at 3:46 at Trumps rally just hours before he was shot. Imagine my horror when after attending rally I heard this. The video shows the building the gunman used it also shows a blurred imagine that might be the gunman on the roof . My only explanation of the audio is the camera was in slow mode something I didn't do intentionally.
