There's no reason to believe he was up there for a long time. He may have fired the minute he got to the roof. Just because you're good doesn't mean you win.
I mean yeah, however people pointed at the guy on the roof before it happened, so to me law enforcement should have got wind of what was happening before he fired, not only that but the snipers that were with the USSS clearly didn’t spot the guy moving around on a nearby roof until it was too late
hey it's not our guys that declared that anything a president does is automatically legal, even something like this. you folks fought for and pushed that ruling through. you'd have to be a special kind of dumb to get upset that you're getting shot at when you've expressly legalized the act of shooting at people. great "law and order" move guys, you legalized all the so-called "biden crime family" actions to make sure your guy can do whatever he wants when he becomes king. i guess they're just the normal biden family now thanks to y'all.
