damn, thats tough. dont think the ages should matter, but the guy was obviously filled with so much emotion, the incident probably happened so quick and split second decisions were made. His life will forever be changed because of this. Im sure if he could go back he would probably have still shot the kid but once he came back maybe not fired shots. Just happened so quick that he wasnt thinking about the law or any consequences or what is or isnt acceptable. Just wants to make damn sure the threat is removed. Then there are all the damn movies where good guy shoots bad guy once, assumes bad guy is dead, relaxes, then sneaky bad guy either nails or damn near nails good guy, good guys girl, or good guys best friend.
Never can be too sure, wonder if the guy could get away with a temporary insanity plea since he might have been temporarily insane at the time. Dont know many people who would think clearly in those types of situations.
