I don't know, and at this juncture it's irrelevant. Like shanek you flat out refuse to discuss the base figures and instead ask for more detailed stats to be presented.
Oh, we ask for details! How horrible!!!
Do you really need in-depth stats to see that there's something seriously wrong here?
There is something wrong; no one is denying that. But you have not shown that this wrong thing is legally available firearms.
If you admit there's something amiss, but deny gun control is part of the answer, then please state what solution you propose.
End the War on Drugs and all other victimless "crimes" such as gambling and prostitution. You'd see the black market all but dry up, there's no longer any profit in turf wars, violence goes WAY down, organized crime withers.
