Are you an idiot? Seriously, dont answer that... the article said they had already crawled out of the neighbours house and were on the man's lawn, backs to the shooter, which means they were fleeing. The man even said he was going to kill them. This is why I'm against people having guns.

He had a gun to them, he could've been like "Don't move or I'll shoot your goddam brains out." and wait until the Police arrive. If they did move, shoot with a miss, and if they still do it, shoot one in the leg so he can't run away. But why shoot to kill when no one's life is in danger?
