There is absolutely no need for semi-auto, military grade weapons in the hands of the public.

16. I think more stringent background checks and emphasis on disallowing access to unfit persons.

A hicap magazine ban sounds pretty good on paper, but in reality, there are already so many out there (probably tens of millions) that ban wouldn't impact the supply of them for decades. I also think making even the already existing ones retroactively illegal for possession would violate some sort of ex-post facto laws or something. Even then, as I mentioned before, even if one could magically poof them off the planet, I doubt that mass shootings would be significantly impacted since magazine changes are so simple.

Short of repealing the 2nd Amendment and limiting people to revolvers, bolt-rifles and shotguns (basically eliminate semi-autos), I'm not sure there can be anything done from a legislative point of view to curb mass shooting gun violence. I think the best road forward in the immediate future is policy changes surrounding the gun culture and trying to better control access to firearms by unfit persons. An end game of limiting actual amount of firearms in the public will require more time and planning, I feel.
