How about the closure of the private seller loophole, waiting periods for guns (1 week for handguns/ 3 months for rifles), a limit of the number guns an individual can buy, a centralized gun tracing system, and a more extensive background checking system that looks at mental health/school records. These are some of my ideas but I thought most of your ideas were very interesting. Also, in number seven do you want guns to be created that only activate if the owner uses them? Do they make any like that?
