12-15% of the general population. 25+% of the prison population. And the Justice Department still has not shown, in spite of repeated assertions, that there is a verifiable bias.
My magic permission slip proves that on one day several years ago I did not have a record of any disqualifying conditions. The fact that magic permission slip holders are less than 0.000001% of those arrested for "gun crimes" is merely anecdotal, just as is the fact that magic permission slip holders are 10+ times less likely than cops to be convicted of any felony - and we know how darned hard that is.
But it's not a white thing, or a black thing, or a yellow, brown, red, or purple thing. It's that criminals see getting arrested/locked up as merely a cost of doing business while non-criminals are afraid near to death of the loss of their freedom so tend not to do stuff that could cause it to be lost. Is there a correlation between that and being a victim who is not responsible for their actions versus accepting personal responsibility for behavior? I don't know that anybody has "proved" it but it is a prevailing theory.
stay safe.
