Whenever this type of thing happened at Charles Xavier's School for Gifted Youngsters, the kids just fought back and took care of things themselves.
True, give one kid wolverine claws, another glasses that shoot matter from their eyes, and we're set.
I have a Kel Tec 12. I mostly have it because it's cool as shit. I would use it for home defense, but I never shoot it, and wouldn't be comfortable using a weapon I'm not totally comfortable shooting
I said "buy", and not "possess". Let someone who is over 21 buy it and be responsible for whomever else has access and use of it. Don't get me started on age of consent. I don't think you should be able to do just about anything before you're 25. I'm no standard.
I keep a handgun in the nightstand in case an intruder breaks in, and I need to quickly shoot myself so as to avoid meeting new people.
I think I'm going to get the tax stamps for an SBR and a suppressor. I have no need for either, though.
