This poor guy murdered a kid in his yard. It takes a brave man to kill an unarmed person who hasn't exibited any physical violence, just verbal insults.
No murder occurred. The only reason they were at the man's home was to give the son a severe beating. The insults were just part of the threats and promises to commit the beating, which is a felony. The only reason they didn't jump White and his son to commence the beating is, because White had the gun.
