I can understand your feelings, but the problem is that most people don't get it. I don't think there would be any outrage against our GIs if no pictures of prisoner "abuse" were released.
If the media are too afraid to play the video of Nick Berg getting his head torn off, the least they can do is to play it right up to the point where they all pounce on him. Him just sitting there with the goons behind him is nothing. Americans need to be shocked for this to be effective.
