The guard was shoved and badly injured, not shot.
It's weird the way that info came about.
I swear, the night it happened, I was watching local Atlanta news coverage, and the trauma surgeon gave a press conference. He very clearly stated she had a glancing bullet wound, emphasing the fact that the bullet didn't enter her skull. He also very clearly stated that there were two head wounds, one caused by the bullet, and one by impact from a blunt instrument, which was worse than the bullet wound.
Bullet wounds are very distinctive, even glancing ones. Atlanta trauma doctors see plenty. I don't see a trauma surgeon being that wrong or misinformed.
Just IMO...but I smell a rat.
