Even though I think the shop owner was completely justified in doing what he did, I also feel with the family in the fact that he was shot twice while fleeing without any money (most likely) and was already fatally wounded. There wasn't a need imho to fire as he was fleeing.
i have to disagree with you there, once you get to the point of having to use deadly force you keep shooting until the threat is completly neutralized fatally wonded or not. for all the store owner knew ompletly nutralizedhe was fleeing towards a corner to take cover and return fire.
