That's all fine and well but it doesn't address the fact that police often practice white privilege when dealing with the pubic. Whites often get the benefit of the doubt, blacks often do not.It's too bad that your thinking on this has been so perverted by the political propagandists that have perverted it.
You seem to understand the problems associated with the situations into which these human beings acting as police are placed.
Assuming that the problems encountered are created by police who were called to help solve the already created problems is an interesting twist in your logic.
People seem to do the best they can do with what they have to work with in any moment. They sometimes make bad choices or mistakes.
Police are people. Police usually are dealing with other people. The more people that are involved, the exponentially greater do the chances for idiocy increase.
It is safe to say that problems implied by any interaction between increase when idiots are involved.
From what I've seen in my short life on this planet, police deal with a higher percent of idiots in their daily actions than do most of us.
Those racist guys in GA that gunned down Armaud Arbery were guilty. But they were initially let go by the local police.
If those had been black guys who chased down a white jogger and killed him I don't think they would have been let go by the same police that let the good old boy white guys go.
