In the early 1990's, the Bosnian Muslims hired a PR firm (I believe either Ruden Finn or Hill Knowlton) to do precisely that same kind of fabrication of media images, and the US government actually took the Islamic-terrorist side against the Christians in the Bosnian civil war - and all claims made by the Islamic-terrorist side have been shown to be utter fabrications.
The mass media have proven themselves to be willing accomplices of evil, and are morally no better than Leni Riefenstahl.
The U.S. did the exact same thing in 1990 in the months leading up to the Gulf War. Those stories you heard of alleged "atrocities" by Iraq troops in Kuwait were completely fabricated. The high-profile New York PR firm Hill & Knowlton was retained to lead the propaganda campaign.
Interesting (and not coincidental) side note . . .
The Hill & Knowlton representative who led that effort was Victoria Clarke, who later served as Assistant Secretary of Defense for Public Affairs in the second Bush administration -- and became something of a celebrity when she was giving daily press briefings on the war in Iraq in 2003.
