The problem with guns isn't that they're inherently dangerous, its the damage someone bent on harm can do with one

To criminalize an unthinking and inert object while doing nothing about the thinking being who wields it, is to not only turn the purpose of the law on its head, but reality itself. Further, any law introduced that bans certain firearms (or any firearm) will NOT be complied with by the very people who pose a danger with guns (criminals). You will do nothing but embolden criminal activity while decreasing the options peaceful people have to deal with such aggression. All the gun-control schemes I have seen proposed are a "feel-good" solution that solves nothing.
