If you are trying to talk about the paradigm of police and black encounters being racist prima facia, that is something that will take a moment to unwind. Police have more encounters with black people per year for a very long time. It had actually gone down significantly in the 70's to only spike and stay high in the 80s if memory of the stats I once looked up holds true. The problem is that there 13% of the US population, around 40-44 million people, are black in this country but commit 50% of the murders. More if you count homicides. News sites will just point out that 76% of police encounters are with black people who make up 13% of the population so it must be racism, but that story isn't the full story. Which means that conclusion is wrong. I am not saying there aren't racist cops and racist encounters out there, but there is a problem with certain areas of the country and black communities in those areas. It is not a problem everywhere, because outside those areas, you'll find that police encounters tend to match the demographics. Areas I am talking about are heavily gang controller urban areas. This is where the vast majority of police encounters in this nation happen. Especially homicides and murders. A racist would look at that and say black people just have a propensity for it, and that is what makes them racist. It has nothing to do with that. There are many a paper, journal, and research project into this dynamic as to why this has happened, and there are a ton of variables to deal with. None of them are causation, but I think the sum of the issues has led to the current situation. Everyone wants an easy answer though and racism is easy. Either by applying racist labels, like it just what black people are, or responding that it is the result of only racism from whites that has put these communities where they are.
Here is a decent article about this topic.
Race has little or no direct effect on the rate at which black men are shot by police.

Basically this article, like many that have done this research, have stated that the number one predictor of someone growing up to be a violent criminal is a single/no parent household. It is the same statistically correlation across all races, all socioeconomic levels, all ages, all sexes, and darn near all countries. Those areas of the countries with the highest crimes rates also have the highest concentrations of single/no households. Until that changes in those communities, I doubt there will be significant changes to other criminal stats.
Just automatically assigning racism as the answer though is a cop-out for an easy answer. It solves nothing. This country is far less racist today than any other country on the planet or any country in history. Race baiters though want to have you looking at every instance of wrong done to you has being something that was racially derived. Either directly or systemically. It makes people angry and afraid. People afraid and angry are easy to control. Fear and sex sells for a reason, ask any marketing firm. Baser human emotions are easy to exploit.
I am pretty sure though the usual gang of posters will come after my post and ask me again something stupid like is the KKK giving me a paycheck, or how I have too much white privilege to even understand racism, or something else along those lines. They rather spout epithets than have an actual discussion.
