Media Matters has obtained video showing a member of the Fox News production crew stage-managing a 9/12 protest crowd for a Griff Jenkins live shot:

Although this video provides a clear-cut example of Fox propaganda in action, the only thing truly shocking about it is that it won't wake up real journalists to the fact that just about every single thing you see on Fox is manufactured. They are an infotainment channel for conservatives, not a real media outlet.
