 Not just the reaction of what took place on stage after the shots were fired, but before that. Now, the Secret Service counter snipers and Secret Service personnel are bound by typical U.S. use of force rules. They can't just shoot somebody because they see somebody. They have to make sure and identify it's a threat and make sure that the threat is actionable. In this situation, you're talking about a threat even 100, 120 yards out. That is not an easy thing to see from a rooftop perspective.
