IDK what the history is in the UK, but the entire history of the police in the US is in promotion of keeping the ideals of slavery in place while the language has evolved around it.

You don't even have to look very hard to find the history. If you don't know it, then you're not trying to know it.

I'm not blaming or shaming any people who are police. I'm saying that even if everyone in the entire police and judicial system as it stands today were a good person, we'd still see widespread oppression of black and poor communities. The laws have literally been created to keep those communities in prisons and to strip away their right to vote by creating laws which criminalize non-violent behaviors as felonies.

Calling someone a criminal over a law that was passed to specifically criminalize non-violent behavior is a huge problem.
The US has an obscene number of its own citizens incarcerated, and we have the gall to call ourselves the Land of the Free. It's clearly BS. It's clearly a problem. Blaming the police or the people they persecute is missing the point entirely.
