That would actually be a good point if this weren't point-blank, which in my experience (albeit with foxes and turkeys) tells me tends to go somewhat differently.
Has Zimmerman denied shooting explicitly to kill or are we in the business denying it for him? If this is something that's been talked about in circles more familiar with the case I'm willing to grant you this element of the point.
Uh huh. You've been able to shoot moving foxes and turkeys in the legs while avoiding their body, consistently, while said fox or turkey was mashing on your face?
Said scenario makes it far more likely that the perp would get shot in the torso. It would be far more difficult and dangerous for someone to attempt to shoot the perp anywhere else as you endanger yourself to richochets.
Why do you think policemen are taught to shoot the torso?
Shoot to wound is of course a sad illogical statement. The assumption of course is when one shoots that death is a possible, if not likely, outcome!
