Mandatory classes on use and safety should be a must, not just for owner but for anyone who will be licensed to use it. Not only should each and every gun be registered, but the owner, and anyone in the household, should have a use and safety license for the same. I'm not sure how one could go about proving the need to own one for protection as that seems rather subjective. But I think gun owners should/could provide proof of how their guns are being safely stored, and that perhaps a standard needs to be set for individual home accessibility. I also think there need to be very strict laws in place for illegally owning or selling, especially if that gun was used criminally. And if someone uses your guns, because of lax accessibility, I think owners need to be held accountable to the maximum. These are just ideas off the top of my head that do not prevent anyone from owning a gun, not one iota. But increase the liability on the owner and the seller for every act that gun commits, no matter whose hands are on it, might make people think a bit more. Oh, and insurance ... do gun owners need liability insurance, or insurance of any kind? Maybe that, too, should be in there somewhere. If you equate that to owning a car, you need to be licensed to drive one; you need to be insured; and you are held accountable ... mostly ... I don't think in this country drunk drivers are held accountable strictly enough.
