NY Times article on how the US military is controlling the images of the war.
after five years and more than 4,000 American combat deaths, searches and interviews turned up fewer than a half-dozen graphic photographs of dead American soldiers.
I personally think that if you need to worry about PR to fight a war, you're doing it wrong. Respect for dead soldiers is one thing, hiding images that show the suffering of thousands is another. I'm not posting the next link for NWS reasons, but you should definitely take a look and think about the effects of an experience like this.
