As with any documentary, there is some bias. And this one does not paint Neo-cons in a very favorable light.
I'm less concerned with what this has to say about Republicans, and more concerned about what this has to say about government generally.
Basically, both sides of the aisle use fear. (I should have found a documentary, that pokes at the liberal tendency to over blow gun deaths)
Its not that they use fear. It's that we all know they do it, and revel in our ignorance.
