Thomas Matthew Crooks almost assassinated President Trump from the roof of a building. We know as little about his marksmanship than we do about Robinson.
It was that last minute turn of his head. Otherwise, the shooter may have been successful. Thank You Jesus!!!
At that range both easy shots for a marginally competent shooter. Crook's shot was good but Trump turned his head. I would assume that Trump was wearing armored vesting beneath his suit and thus he went for a head shot. The evil bastard that killed Charlie Kirk did the same. I suspect he was trying for a head shot and aimed a few inches low and thus hit his throat. Still it was a good shot from that evil man.
With an M1-Garand with no scope, I can make a sure head shot at 100 yards and a center of mass shot at 400 yards. It is not difficult for an experienced shooter. This guy was a deer hunter and well withing his skills.
