Along with this discussion of war photographs one must not lose sight of the use of manipulation, fakery and staging in such photographs. The most famous is the Mt. Sarubuchi raising of the flag which was actually a recreation of of the actual event with a much bigger American flag.
We also know that Sadam used corpses that had died from causes other then war to display to gullible news organizations in the first Iraqi war as casualties.
The US military is very good at showing only the successful smart bomb strikes and Patriot missle intercepts.
These practices go all the way back to the Civil War where it was common practice for photographers to move corpses into more pleasing compositions.
Finally, correct me if I am wrong, but hasn't the famous photograph by Capa of the Spanish soldier being shot by been debunked as staged?
