So yeah you can fire a bullet so many different ways, a rusty nail and hammer will do the trick. Isn’t the real problem the frickin bullet?
I swear in Sweden or something, you can take a gun home but ammo is only sold and consumed at the range and not for taking home.
Sure, you can make this a hollistic approach regulating guns and ammo, but the ammo seems to be the bigger issue here. You can make guns easy peasy, but ammo is much harder to manufacture and easier to regulate.
Just to have fun by being a bit pedantic, the a bullet is a possible source of toxic lead, and if you are using the colloquialist ‘bullet’ to mean a charged cartidge containing a bullet, the gunpowder charge makes it a tiny bomb, which can be dangerous as well, even without a gun, especially when exposed to idiots with hammers or fire.
Playing along…
If a lead bullet in a charged and primed casing sits undisturbed in a crowded room, it will neither poison people nor discharge itself
