I've always said gun banning doesn't work. I like to point to the U.K. and Australia as prime examples. Turns out, I'm even more correct than I'd thought. Evidently the U.K. government has felt a great need to under report gun violence, since naturally they banned them with the intention of doing away with gun violence.
I guess the old, often mocked by the gun banners saying is true: If you ban guns, only criminals will have them.
