Is it not interesting how data can be manipulated, to meet ones own requirements (no finger pointing). I think there is little conclusive evidence either way. So any change either way may only make a small change.
So let bring anew one into the mix, how many cars are used as the weapon of choice for the purpose of homicide.
Which then has the higher ratio guns or cars?
I doubt if even I could find any empirical data on that particular ratio.
However I would suggest that, in this case, the gun would be used more in a premeditated manor than a vehicle
