Doesn't the 5.5/100K number of fatalities for the USA include the number of self-inflicted gunshot casualties, not just homicides?

I'm not certain I understand how you can say this isn't supposed to be a pro/con gun control thread, then ask folks to pay attention to the Sociology, not the logistics. Gun control is all about what sort of society you wish to be, and whether you're willing to sacrifice justice for safety.
