Fair and Accuracy in Reporting explains how most of the corporate media treats murders committed by the virtuous US military:
Early reports of a massive U.S. attack on civilians in western Afghanistan last week (5/5/09) hewed to a familiar corporate media formula, stressing official U.S. denials and framing the scores of dead civilians as a PR setback for the White House’s war effort.
Scanning the headlines gave a sense of the media’s view of the tragedy: “Civilian Deaths Imperil Support for Afghan War” (New York Times, 5/7/09), “Claim of Afghan Civilian Deaths Clouds U.S. Talks” (Wall Street Journal, 5/7/09), “Afghan Civilian Deaths Present U.S. With Strategic Problem” (Washington Post, 5/8/09).
As is frequently the case with such incidents (Extra! Update, 8/07), the primary fallout would seem to be the damage done to U.S. goals.
