Outside of "cartoonland" are normal people, including those who are not corrupt or just want to get through the day doing their particular line of work. Quite ironically, you seem to only be able to view other people as a group through the childish lens of fiction where it is perfectly valid for "all x characters to be y" without exceptions.
Also, is "cult of Justitia" a reference?

That most series portray police as "just" is a byproduct of focusing on a protagonists pool that the audience should find reason to idolize or admire. When police are not used as "the plot demands it" obfuscation tools or villains (or victims), they typically get a flat portrayal. If you talk to them off-duty, asides from a few neat stories, they're people, both shallow and well-versed are represented.
