GregBurch: The USA have the highest number of homicides by firearms per 100,000 citizens in the world, with 3.72. Twice as high as Italy. Six times higher as Switzerland. Germany has only 0.22.
It's interesting that you make this assertion, since it's not true:

or, interestingly, you can look at this table:

... which uses some earlier statistics to rate the US somewhat lower on the list/
Now, it's true that the US is far higher than our oh-so-civilized brethren in Europe. What I find interesting is the comparison of gun homicide rates to gun OWNERSHIP rates. There are countries with very high gun ownership rates (viz, Finland, Israel, New Zealand) that have far lower gun homicide rates. To me, the very interesting question is why?
Similar ratios on unintentional deaths by firearms. Do you think, this can only be explained by drug related crimes? Can somebody look for similar statistics for drug addicts per n people? I don't find something unbiased with my english skills.
I was being a little oversimplistic, but the real explanation is cultural. There are culturally identifiable segments of the US population that have very high rates of gun ownership and relatively low levels of gun violence -- basically down with our superior European brothers.
I leave the question of what cultural factors might explain the difference in gun crime rates across relatively similar levels of gun ownership for you to ponder.
... and let me add that I don't think it's the drug USERS who are the main perpetrators of violence. It's people involved in the illegal drug business. Just like it was in the 1920s when a different drug was illegal in the US.
