I might be wrong, but isn't everything on there already a requirement? I think the mental health check is the only thing that isn't (unless you consider losing your right to own a gun after being involuntarily committed for any reason to be a mental health check). The problem is that even our existing gun control laws aren't being properly enforced (otherwise that wouldn't be part of the poll). I think there needs to be more gun control. I'm just not sure that more gun control is going to work because the government won't enforce what's already there.

I personally think a licensing system similar to what we have for cars would help a lot. Want a double-barrel shotgun? The current system would probably work for that. Want an AR-15? You need the enthusiast license which involves a week or two of training, a basic mental health evaluation, and a gun safe (not a flimsy lockbox) to store it in. Want a .50 cal, belt-fed browning machine gun? You gotta get the super ultra deluxe license that requires a year of training and mental health checks, background checks complete with colonoscopies from the FBI and ATF, and you still need a gun safe to store it in. Finally, if your gun is used in a crime then you're considered to be an accomplice. Your only defense is if you can prove it was properly stored and you reported it as stolen within a reasonable amount of time.

Edit: I got it guys, I'm wrong about existing gun control. I'm leaving the post up because there may be others who are also confused about it.
