She really needed much more lethal ammo. I bet it was some of the cheap ball ammo that’s mostly good for target shooting. Also, from some of the other reports I’ve read, it looks like the perp had done some time, meaning he was probably rock hard. All the more reason for a larger caliber pistol, more cartridges, and stronger ammo.
That FMJ stuff is all most walmarts carry. It is a lightly loaded round, but at least she had good shot placement. 5 out of 6 COM under high stress is better than most cops can do.
