Sure, that is totally the same as a mugging that took place on a street where the robber is at point blank range.
Also, that man was an asshat for opening up right there. First he uses a co-worker as cover then keeps shooting with a toddler right there. How close did he come to shooting the toddler?
How many shots did he fire? It didn't look like he shot the robber, where did the other bullets end up? I for one would like to get shot by an errant bullet because some jackass decided to play Diehard over protecting someone else's money.
