And shoot a guy in the groin (upper leg?)...
Lots of details aren't out there yet.
Well, I've never shot anyone, but I have shot a handgun at a firing range and its not like you always hit what you're aiming for. I was a few feet off of the bullseye for several shots and that was with time to aim. I think someone in a high stress situation on the move could easily hit someone in the leg while aiming elsewhere.
