Here's a related story, Report: US soldiers 'unlawfully' shot Reuters cameraman in the Chrustian Science Monitor of April 12th:

US soldiers breached their own rules of engagement when they shot two members of an Iraqi camera crew working for Reuters last year, an independent private investigation has determined. Editor & Publisher reports that the investigation, which was commissioned by Reuters, also said that the shooting was "prima facie unlawful."

But I don't imagine there'll be too much in the media about this, any more than there is about the Haditha killings. It's the wrong people getting killed, I suppose, people with names like "Walid" and "Khaled".
