I was seat-of-pants estimating the percent of black males as described below. and got this data from:
Federal Bureau of Investigation Crime Data Explorer<.b>
Blacks are 12% of the population, males are roughly half that, so six percent, and I read 40% of black males have a felony conviction, so I just round it to say, 3% with some portion of that being violent crime, let's say half of that, so that makes it 1.5% of the US population responsible for 36% of all violent crime between 2010 and 2020. (All blacks, male and female account for 45% overall, and on the same website, violent crime broken down by sex shows women are responsible for 20%, so I multiplied .8 x 45% to get the 35%.
Here is the graph not broken down by sex:
It is a disgrace.
If you had a town of 10,000 people experiencing a high level of violent crimes, and you could narrow it down to 150 men causing more than a third of it, you would expect a crackdown to put those 150 men behind bars or run them out of town.
