Kevis Sites is an anti-war activist and a Pulitzer Prize hunter photographing a war.
When you think about it, Kevis Sites was in a position to "break" a big story no matter what the Marine did. If he had hesitated and someone else was killed, Sites would have used the same film to "prove" the lack of training and/or other gneral "unworthiness" of our troops.
The only way that justice could have been served is if Sites had been the only casualty. If I were Sites, I'm not sure I'd like to stay "imbedded" under those circumstances.
