Another idea is to not allow private gun sales at gun shows without background checks. So lets make it a crime for you to also sell your car to a private individual unless you run a check to prove they have a valid drivers license, proof of insurance and have not had any accidents or speeding tickets in the past 10 years.You see and I have said before this is the trap you fall into when you let politicians argue you don't need a AR15 with a 30 round magazine to hunt deer because they are correct but the simple fact is the second amendment was written not for hunting or home protection but for protection from government abuse of power.
If you want a common sense solution to the evil black rifles just make it a law to make them all pink or white and only the military and police could have black rifles. I could support this kind of legislation because after all making evil rifles black is a very underhanded form of racism. We would also have to ban black spray paint or at the very least don't allow it to be sold without a background check. Now I think this would be good legislation at lest till someone uses a sawed off shotgun to kill with then we will have to look at banning hacksaw blades but I think would draw the line there.
