 Hey, there's a guy up there with a gun. Maybe you should do something about it. We've also just learned that there were two counter sniper teams on site and that the counter sniper did not need approval to shoot. One source telling NBC News that prior protocols were not followed. Here is a man who was right there and he told the authorities, hey, there's a guy on that roof with a gun. And listen to the rally, right? We couldn't see him, but we could hear him.
