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.
I retired 22 years ago, so have no idea what weapons they use now. I'm assuming they've upgraded from revolvers though. I could have purchased and carried weapons on my badge, but I never wanted a weapon. I was a divorced mother of two sons, and never wanted to put that kind of temptation in front of my kids, especially since I had to be gone at least 8 hours each day, and sometimes 16. It wasn't worth my while to buy a gun safe, since owning a weapon wasn't anything I was interested in anyway. A large number of the men I worked with were hunters, and some carried their personal weapons to work each day, which they would have to unload and leave at the arsenal before being allowed inside. Their weapons sat in the arsenal as long as they were inside, and they had to pick them up on the way home. One day an officer I worked with, forgot to remove his personal shotgun from the cab of his truck when he parked on State property. A Lieutenant noticed it, and he was relieved from his job, and sent home to get rid of the rifle. He got written up for the incident, but fortunately didn't lose his job.
