The CSI episode is not a documentary. And you can always look at the documentary maker's past works (unless it's the first project) and see if the reporting is biased or neutral.
The problem is that the majority of people who see documentaries take them as being completely true without fact checking anything.
If you decide to make a documentary you either make it as truthful and realistic as possible, if you can't do that then you shouldn't be making one in the first place. Anything else you could view as propaganda.
