I'm genuinely interested—is this the consensus opinion of most of the developed world outside of the US?

I'm a US citizen, and generally consider myself liberal and progressive. I favor much stricter gun control laws. But I'm not sure I do favor complete disarmament of the citizenship. I do believe that the knowledge—not the use—of citizen's arms does provide a reminder to the government in times of crisis.

But am I simply experiencing large cultural bias? Is there any research on this? Any evidence I can look to? I'm very curious.
