In this episode of Criminal Minds, the BAU goes rat hunting in “Internal Affairs”, even though it’s a different branch of government and all the conflict about policing your own is lost. Didn’t we see The Departed, anyone? This is all part of the Season 11 Dirty Dozen we are obligated to cover it eventually, but we’re so darned annoyed by this storyline that we’ll only give 100% instead of 110% like usual.
