Au contraire, it's a problem for any country that thinks it appropriate to carry guns around in public for no particular reason or purpose other than because its some stupidly interpreted "right" that made some sense a few centuries ago but does not now.
Ah, but they need those guns to defend themselves against people with, well, guns. The NRA has been allowed to do quite a number on the psyche of that nation. Personally I'd be more worried about getting accidentally shot by such an idiot or their police than getting robbed - that seems nowadays a relatively minor risk in comparison.
