I'm not sure if we watched the same show, I recall them doing all sorts of harmful and/or illegal things that most decent people would not find relatable at all. It definitely doesn't portray them as the deliberate organized evil that real life law enforcement actually are, but it's a comedy and this is the US it never would have been greenlit in the first place if they did. I think it does a good job of undermining the public image of US law enforcement in a way that deeply indoctrinated Americans won't immediately dismiss as hostile.
