Not gonna argue the fact that the bad guys getting dead and/or put out of action is a good thing; it is. As advocates of using a gun for self defense we have to look at this critically, though. The defensive shooter is extremely lucky that things didn't go bad for him. Specifically, the article states that he went outside, then back inside and retreived a rifle. He then went back outside and fired at the fleeing vehicle "hoping to hit a rear tire and prevent them from leaving", according to the article. That action right there puts him, in many jurisdictions, at risk of prosecution. I'm glad things worked out for him; some of his actions were not the best, though.
