The anti-gun brigade always like to point to the US and the high crime and murder rates there correlated with the high level of gun ownership there. But across the border in Canada, they have a very low murder and violent crime rate and gun ownership dwarfs even that of the US. Hell, most houses in Switzerland contain assault rifles, yet its one of the safest places to live in.the.world.
Gun crime is only loosely linked to gun ownership rates. Its more about a culture of criminal violence than anything else.
