Get this: A Mugger comes up and takes your wallet, then you pull out your iron and mag dump into his or her spinal column while they're running away, you take your wallet back and continue your walk to the store or whatever. In some bleeding heart liberal areas you can go to jail for that. Grade A Nutjob law if ever there was one.
