Guns are not designed to kill people

While we’re waiting for evidence that general military service pistols did not exist during the Revolutionary War, let me pose a question:

Why do foreigners give a damn what we in America do with our guns?

I mean, with folks in Canada, I can understand; we have a ~3,000 mile common border, and could conceivably be a source of illicit arms to Canadian criminal elements via smuggling and such.

But England? France? Japan?

Why does it matter a whit to any country that doesn’t have a border with us what we do, domestically, with firearms?
