I think you would have to change the 2nd amendment to do what you want,and I really dont think you want that. The more rights that are taken away the worse off this country gets. The best thing to do is make it mandatory for every American citizen to learn how to use a gun and have one. This should be subsidized by the federal government. Do the proper back round checks that we do now. Then it should be open carry. That will end a lot of violence.
