Listen up lady, you can easily compare two countries however big one might be compared to the other, if that wasn't possible, then you could just use that "LOL YOU CAN DO THAT, IT'S LUDICROUS" line every time someone had a point to make whether that might be school system, health care, per capita income/childdeath/crime rates and so on. As Aram also pointed out, it probably isn't out in Happyville, Ohio that graph for gun crime in the US and A rises, but rather in the more populated (and socially unstable?) areas of the major cities. I won't even dare to think what would happen if you'd suddenly get a full auto assault rifle with you home after having served there. :D
Your frontier homes might needs guns for whatever reason, but that won't exactly fly in the cities, unless you just need it to blow up the guy standing in your bedroom. (get one of those flashlights that Aram has instead of a gun, much more effective ;P)
And if you can't figure out by now why we're curious, then don't bother at all.
