WIFE: "If you are going to threaten me and abuse me, just make sure you don't go out and try and buy an AK47, Okay?"
HUSBAND: "O.K. dear, when I come back tonight and to beat and rape you, I'll make sure I'm not breaking the law and using an illegal weapon. I wouldn't want to point that at the the cops when they show up to confront me. That would be illegal and they may throw me in jail."
I imagine a cop going up to a car that he has pulled over would be much more concerned about a handgun than an AK. It's pretty hard to conceal an AK and then do a quick draw with it.
