Why are you only counting deaths from guns? Are people killed by other means not equally dead? 

What he said is absolutely true and the only meaningful measure for cross-cultural comparison of criminal homicide, if your concern is truly public safety and not hatred of guns.

People serious about killing themselves use the most effective means available to them in every society. We do not have the highest suicide rate among developed countries, in most hanging is the most common. In the US guns are used primarily by adult, white, male, gun owners. Not sure what gun control law could change that. In any event, per the CDC, the percentage of suicides, for both men and women, using firearms has -dropped- significantly over the past decade, with hanging increasing.

In any event, for a host of demographic and cultural reasons the US homicide rate, while low globally, has been higher than the only facilely similar 'usual suspect' countries trotted out since before any had real gun controls.
