A look into American popular culture is rather revealing in this aspect. Consider the currently running series "SWAT", which portrays the rise of a good-cop SWAT leader. That's the lead "good character" of the series, and he and his team are brutalizing suspects, some instances of which may actually be torture, commit various felonies on a "dime a dozen" basis, constantly abuse police powers, lie to superior officers, frequently recklessly endanger civilians and commit morally despicable acts like blatant entrapment and much more.
Those figures are the good cops in media. This is the popular media idea of "policing done right" in the US. While just one particular example, but if you look around in American media the "good cops" exhibit at least some of these aspects the grand majority of the time.
