I think you are starting off with an incorrect premise: In the US, the role of the cops is not to keep people, or society safe. It often also has very little to due with “the law”.
The role is to keep the rich and powerful, rich and powerful. They are meant to oppress people, and keep the slave-machine running. Cops shooting people, stealing from them, escalating situations, and not knowing the law is the intended situation.
In that sense, the cops are doing their job to great effect, and don’t need any more training.








Then why are you mad at AI? Those fit all of the same requrirements that you listed above. Why do you think one is bad, but not the other?
