Looking at that diagram showing kids position in relation to trump and the sniper that shot the kid, it's bizarre that he could get a shot off before being spotted.
I heard people saw him, including the SS, but they waited to make sure he had an actual gun so they didn't just waste a kid.
But I have a hard time believing that cuz if they have to wait until someone takes a shot before they do anything then what's the point of even having security?
