In all of the discussions of gun control - bans, registration, etc. - there’s also the faction that wants to restrict the availability of ammo. No ammo, no shootings.
I have to wonder how much ammo a gang banger really needs over the course of his “career”. After all, they don’t practice or shoot competitively. Seems like a few boxes would do it.
The 18th Amendment didn't stop the importation or consumption of spirits; high cigarette taxes encourage cigarette smuggling today. Would offshore ammo factories pop up and smugglers make a fortune on ammo? Of course.
