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

I've been watching The Blacklist with my wife. I've remarked that it's very honest in it's portrayal of law enforcement, in that they are all dishonest, corrupt, and criminal.

Not really a fan of the show, but I love James Spader's portrayal of Raymond Reddington. I lose interest when he's not in the scene. Just wanting to watch him has gotten me through to season 9.
