What's weird to me is the shot itself. If Kirk is actually wearing hard body armor then it makes sense. Bullet clips the armor plate and then ricochets up into his neck. But it just really doesn't look like he's wearing any body armor at all. You can see the outline of his pecs and his nips. So if there's no body armor for the bullet to deflect from what happened? He didn't just get shot directly in the neck from the front. I doubt the entry wound would have been that big and there definitely would have been a gaping exit wound. So did the bullet hit this cross he was wearing? Seems odd a .30 cal bullet you'd normally use to kill deer would be stopped by something like that. Especially considering we don't see any wound/blood on his chest.
When I first saw the video of the shooting, I immediately thought he'd been shot from behind. So there would be some small entry wound on the back of his neck and it forces his body to tense up like we see in the video, then the shirt billows out and the gaping exit wound appears on the front of his neck. This guy's video seems to suggest a bullet could have come from behind him. A bit morbid but he tries not to show the blood and whatnot. I'm also not claiming any crazy conspiracy theory like Israel killed him or the shooter was a patsy or anything like that. Just find the shot itself a bit odd.
