Is it just me, or does crime documentaries have a biased "pro-cop" vibe to it?

There has been a fair amount of analysis of the social role of 'true crime' as a genre. To boil it way, way down, it's about creating a representation of human evil to let people feel essentially righteous. It is peak centrism, uplifting the status quo by placing it as opposition to the unquestionedly heinous, and with it, current structures, like cops as law enforcement.
