We all need to buy "ASSAULT WEAPONS"

. Then we can sell them to each other. Then..... when they call you about your weapon. You can say, "Oh, I sold that ages ago". (Don't have to tell them about the AK you bought off some guy. And there isn't a record of that sale anywhere)
No record of the say between me and you? That is a good thing. Well, unless your keeping a record of sales. Which defeats the idea.
