Which happens because black people are overrepresented when it comes to crime, which happens because they are overrepresented in being poor as dirt.
There is racism in the police force in the US, no doubt, but constantly dealing with criminals and seeing a disparity in a race is bound to make people racist. If you were to wave a magic wand and make all racism in the US disappear overnight, new racism would appear in the span of a month because poor people are still poor. This is why I think BLM was headed towards failure from the very start.
