Exactly my point, Zombie. You leave the immediate area of an armed encounter, if possible, for the same reason you don't sit in the middle of the interstate after being involved in an accident. So you don't get hit again.
I've got near 30 years behind a badge and I would not consider such a defensive repositioning anything but common sense.
I'm inclined to think if a man hasn't gotten his point across in 4912 attempts, 4913 probably isn't going to do it.
