The article said that Jack recieved multiple gunshot wounds? I believe that the law will not be entirely in favor of the homeowner (sadly), I believe anything above one shot is no longer considered self defense. This alleged "drug dealer" may be getting into some shit after all.

I wonder how Jack was convinced by a 15 year old to go do something so stupid. The little kid has fucked up something hard, B&E, robbery, attempted murder, maybe even getting Jack's death pinned on him as a manslaughter. Death penelty? Don't think so, not for a kid so young. Military school would do wonders for that kid, I think.
