 Let me ask you this. So the Secret Service, top brass, I assume they're walking around, checking out, making sure all the soldiers are in place the way they ought to be. And he or she sees the rooftop is empty? In other words, none of their snipers are there? Do they hear the screams of the patriots in the audience saying, there's a guy up there with a gun, a rifle up there, and others who said they saw?
