Do you have any scientific studies to back up any of the claims you have made here? For someone lamenting the appeals to emotion of strict gun control advocates, there is a striking lack of evidence supporting your position.
Much of the information I described is listed on the very page on Wikipedia linked above. If you dig a bit further on Wikipedia you can find the stats on a state-by-state basis. I believe at one point there was a breakdown by race on Wikipedia at one time but I'm unable to find it now.
The FBI's own crime statistics can be rather enlightening if one were to drill down into the numbers instead of looking at the nation as a whole.
The problems with gun control studies are the same as with climate change studies, there are always accusations of bias on both sides. I suggest everyone read studies that purport to show the truth as presented by both sides and decide for yourselves.
