On a more serious note, they didn't because the story matches the action line. The action line is the direction the drive-by’s want the story to go. In this case they want the U.S. out of Iraq. Preferably in defeat, but they will take our being forced to leave by the Iraqi government that we fought to install. Anything that humiliates the U.S. and minimizes the accomplishments on our troops.
If you understand the concept of the action line all the activities of the drive-by's become understandable. If you don't you may be left scratching your head.
Our American Born reporters can go to Hell for the treason and lies they have regurgitated upon us for the past 40 years!
The Foreign Born reporters are already bound for Burning Lands.
