He's 19 and knew how to use a AR 15 I'm sure his dad or mom had trained him for exactly this type of thing he might feel bad for awhile but I'm sure he will recover ONCE SOMEONE EXPLAINS TO HIM IT WAS THEM OR YOU OR SOMEONE IN YOU FAMILY he's probably sleeping like a baby tonight knowing he protected his family and homeGood kid
Too bad he has to live with it, 19 is still on the young side - hope he gets some help and pulls through it.
