@gangstercat if you're legitimately using that as a counterpoint, then you're a lost cause.
You're not even trying to give context to what you're alluding to. Black people tend to be poorer for institutional reasons. Poor people tend to commit more crimes. It's by no means a black problem, it's a socioeconomic problem.
But sure, I'll play ball for a bit. Most concrete numbers I could find were from 2016, so let's play with those numbers. In 2016, about 323 million people lived in the USA. About 13% (the black population is 12.7% but whatever) of that is 41.9 million (let's round to 42 million).
Also in 2016, 1,238,185 violent crimes were reported to the police nationwide. From those reports, a total of 408,873 arrests for violent crimes were made. Of those arrestees,
153,341 of them were Black. Already we see that's not 50% of arrests for violent crime, it's closer to 37.5%.
If we assume one crime per person, that's 153,341 black people arrested for violent crimes. 153,341/42,000,00 is 0.00365. So ultimately, ~0.37% of black people were arrested for violent crimes in 2016.
And all of that is before we even begin to consider: do black people commit more crimes, or are they 4x more likely to get arrested for doing the same shit everyone else is doing?
Blacks and whites have similar rate of cannabis use but blacks are charged (almost 4 times as likely), convicted and sentenced each at a much higher rate than whites. Without institutional racism you would expect similar rates for each of those 3 categories.
