Here's one of the reasons for systematic or systemic fallacy of racism WRT police action.....
About 70 percent of all FBI UCR Crime for 2015 was by Whites, which make up about that same percentage of the US.
About 27 percent of all FBI UCR Crime for 2015 was by Blacks, which make up about 12 percent of the US population.
See an issue? Blacks make up 12 percent but commit 27% of the US Crimes. So 2.25 times as much based on their population?
THAT is why resources are focused where they are. That's not racism by default, which seems to be your impression.
