Why are you surprised? Nick Berg was killed in retaliation for Abhu Graib prison, or so the story goes. So, you see. Berg is Bush's fault, too. That's why it's positioned below the prison abuse photos.
Sheesh, you guys really need to study up on your propaganda techniques.
Berg was murdered BEFORE the prison story broke. The WEB SITE that posted the video obviosly keeps track of US media and is feeding into the media's effort to create a media vietnam syndrome.
