 THE SHOOTER WAS PERCHED ON. AND SOURCES ALSO TELLING CBS NEWS THAT THERE WERE ACTUALLY SNIPER TEAMS INSIDE, BENEATH THE SHOOTER, INSIDE THAT SAME BUILDING THAT THE SHOOTER WAS ON. SO A LOT OF QUESTIONS. THE SECRET SERVICE SAYS THE REASON THEY DIDN'T SWEEP THAT BUILDING INITIALLY BECAUSE IT WAS TECHNICALLY OUTSIDE OF THAT SECURE PERIMETER. SO, CHARLIE, JUST A QUESTION ABOUT SNIPERS BEING IN THAT BUILDING. THOSE WERE NOT SECRET SERVICE SNIPERS? OR WHO DID THOSE SNIPERS BELONG TO?
