Do you actually understand how these studies are made? Almost always one sided to get the result that the PhD is looking for - I know, my son is a PhD and does these studies.
Really, do not take these studies as anything except politically correct for their time...
And there's the stickler.
These type of "studies" are what 0bozo and the other anti-2ndamendment libs will use to try to enact more gun laws.
