I mean, personally, I would note that US police departments are extremely uh, compartmentalized. I'm willing to accept that there are good cops out there, genuinely. But a good cop can only exist in a good department, and the structure of US policing makes good departments extremely unstable - and a good cop in a bad department inevitably either becomes no longer good, from accepting the abuses of their fellows, or no longer a cop, from their coworkers and superiors pushing them out.
