Here are my thoughts from watching that tape:
Talk about a cold-blooded, fast attack where an innocent was shot without warning! Unbelievable. Situational awareness is really important. Luck doesn’t hurt, either.
Open carry was an advantage in this case because in the video I saw just how fast the GO managed to draw his gun and begin to return fire. You always hear about how open carry is so bad tactically – you’ll be the first one shot, etc. Oh, yeah? The GO had a HUGE gun in plain sight and he was NOT shot. Who got shot first? An unarmed store owner.
I am betting that the BG was on drugs, big time. He was hit with THREE 45-CALIBER BULLETS, with at least two of those hits causing grievous injury, and he continued the fight as if he had not even been hit at all! In fact he was strutting like a peacock who owned the place as he was walking up and down the aisles trying to get to a position where he could shoot the GO. As a gun owner, you need to be prepared for that eventuality and keep shooting the BG in his center of mass until he stops his attack. Don’t think one shot, or even two shots, are going to do it. And a head shot might well be what it takes to stop such an attack quickly.
If you are out of ammunition, a gun does make a great weapon with which to bludgeon someone in hand-to-hand combat.
