I have a theory (don’t we all): That is that the agents, Deep State, whomever, allowed the kid to do all the set up, investigation, buying supplies, etc. The kid thought he was certainly going to carry out the hit. They (alphabets) knew everything about him and expected him to go there, set him up in fact, BUT they put someone in the building to take the actual shot as insurance. God turned Trump’s head.
Occam’s Razor…..simplest complete scenario.
My guess is that Crooks killed the fire chief, wounded the other two men, and hit the bleacher railing and the hydraulic hose. The actual sniper fired three rounds in rapid succession just as Trump turned his head. Finally, the defensive sniper shot Crooks dead.
And ballistics will never be revealed.
Americans desperately need these theories; if we learn that our agencies are staffed with bumbling mediocrities, we'll start thinking that maybe we're just as mediocre as anyone else, and that we suffer the effects of original sin just like everyone else in the world does.
(And if we're in the "greatest country in the world", then we certainly can't have that.)
