Your claim about 2014 is wrong. From that link, we know that in 2014, there were 20 million white people and 10 million black people in poverty. If I missed something, please point it out.

We agree that policing is political. But American policing began in Boston in 1838, and was based on the British model. That had nothing to do with slave patrols, as both Massachusetts and England had abolished slavery by then.

What you're doing is called race reductionism—you're comparing racial groups and ignoring class. Because everyone killed by the police is poor, you are much less likely to be killed if you are a middle-class black person than a poor white person. Or do you think middle-class black people have acquired white privilege?
