 This particular shooter acted alone. That is, of course, what they are saying right now. We have no evidence to the contrary. At this point, we're also finding out new details about the shooter. Thank God he was a terrible shot. Apparently, not only was a terrible shot, he actually had applied to be on the school shooting team. And he was a bad shot so bad that they rejected him from the school shooting team, which is presumably the reason he missed the shot. Although, of course, only through the grace of God was President Trump not killed. His head exploded on national television. I mean, truly.
