His friends had multiple weapons. Don't act like he was doing that suit out of self-defense. He kicked the guy while he was out and then calmly talked to the other people. He is probably going to get tried for aggravated assault and felonious battery.
but mah family... A 5000 pound truck and a shotgun isn't enough protection against a bunch of young guys on tiny motorbikes.
If dude actually feared for his safety, he wouldn't have stopped the truck and then gotten out. Why the would you leave your vehicle if you were worried about your family?
