Reports are that Charlie was wearing a Kevlar vest. Alex Jones, who knows a LOT about bullets hitting living things with his lifelong history of hunting animals, says the bullet hit Kirk’s chest, explaining weird movements of the shirt. Then the bullet traveled up to the neck. Being a vertical trajectory from bouncing off the vest, then bouncing upward, rather than a direct, horizontal shot, the bullet probably did not penetrate to the carotid artery instantly, traveling through some flesh first. Also, in the video I saw, it did NOT look like Charlie was on a stretcher, but being carried by his limbs.
