Yes but not in those mass shootings right? To kill a lot of people in a short time, which seems to be the case with the mass shootings and what actually causes all the discussion, you need a machine gun, assault rifles, etc or whatever.
Why are mass shootings special? Mass shootings make up about .02% of homicides, why should we care about them and not the other, more preventable, deaths?
Furthermore, I recommend reading my response to Final-Fan a few posts about yours about this conflation of "assault rifle" with weapons that are legally own-able.
They are special because they bring a LOT of attention, and because usually is related to kids, just it.
I love both volumes of the book "Freakenomics", the first one has a chapter about what is more dangerous to kids in USA, guns or pools. It happens that more infants die because they walked into the swimming pool with no one noticing and died than infants died because they found their dad gun and killed someone, maybe another house infant, with the gun.
And I agree with you, the other deaths are much more relevant in number. But the point is nobody cares if a lot of people died in drug lords wars, but when 20 kids die inside a school, of course, everybody gets shocked.
