The “under-bite” the teeth are also chipped a little. I would suggest this is where the round entered. Between the teeth and the lips up toward the sinus cavity. Though i will say I don’t have enough information to be sure of this.
You have it about right. Early on one of the sharp shooters, seeing the carcass, mentioned the kill shot was in the mouth. He didn’t mention an exit. For reasons known only to the security folks they clammed up after that and have simply left us with those first few observations. My guess, from there, is that there are so many buttz hanging out over their half-assed performance and they are just skeered spitless wondering when the firings start.
The basic notion that as many as eight shots got fired before the dirtbag got his, is way out there on the incredible scale. And the basic idea that a security guy couldn’t take a shot until Trump took a round in the ear tells us that much dirtbagness is afoot. Why the hell would a guy take a job that requires his protectee be injured before he can defend him?
