Guns are a serious threat to human life and should be treated as such.
Yet, with millions of handguns, the total deaths by firearm number roughly 30,000 a year, half of which are suicides which I don't think you can really blame the gun for.
Speaking of suicide, in Japan the suicide rate is more than double what it is here.

In Japan handguns are outlawed and that fact is frequently cited as the reason for Japan's low homicide rate. So how come they have such a high suicide rate?
