They need to ban ammo, all ammo, with only the military and law enforcement agencies are allowed to purchase. Also make it illegal for private citizens to make their own ammo and discourage it with ridiculously long prison sentences, like 10yrs for every bullet/shell made, mandatory.
It's not infringing on the 2nd amendment, as people can still posses and polish their guns and they can aim at targets while making *bang* *bang* sounds, but it's cutting down on the ability for criminals to use guns. Problem solved.
I know I'm not the first person to bring this up.
