I think the woke crew and the Trumpers are as bad as each other.

You're right, more white people are killed than black people by the police, when not adjusted for population - but black people are overrepresented when you do adjust. That argument is also reveresed when people say 'it's always a white guy' who does mass shootings. The reality is, when you adjust for population, it's pretty much irrelevant what skin colour is. https://medium.com/lucid-nightmare/mass-shootings-arent-about-racism-1eec3db4a708 - the important thing is to stick entirely to the stats and numbers.

The police question is a more complicated one. I think high crime and low education are directly a result of poverty, or that poverty has a disproportionately high affect on these things. That's why I argue for economic reform rather than identity politics - decent investment and wealth redistribution by focussed taxing may alleviate a lot of racism. Firstly by lowerng crime and increasing education, and secondly by stopping a dog-eat-dog world at the bottom end of society. Racism is a symptom of inequality as well as a cause.

What the psychology generally points at, is the implicit bias unconsciously shared by a lot of police officers, that black people are trouble. In some cases they may be, because of the high-crime/low education you spoke of, but in many cases they're not. Putting macho and trigger happy cops into the mix means you have a population of people who are wary of the police, a group of officers who are psychologically inclined to unconsciously judge the situation to be a threat and use excessive force early. You can find a good summary of the implicit bias studies here https://www.apa.org/monitor/2016/12/cover-policing

The trick to the centre ground position is to reign in the extremists on both ends. There are people who will argue that racism is the root cause of every ill that ever happens to anyone. It isn't. There are also people who will argue that racism doesn't exist - and perhaps the sort of racism being argued for (everything is racist) doesn't exist to the extent we believe it does - but I trust peer reviewed studies and I'll go back to the stats. It does exist but the reasons are complicated and the current dialogue is making it worse rather than better.
