I guess the answer should be obvious: depends on what the meaning of "truth" is?
Come on. If U.S. troops gang raped and murdered an Iraqi woman the NYT, LAT, WP, CNN, FNC, MSNBC, CBS, NBC and ABC would have gone full page and wall to wall coverage of the rape and murder.
Greta would be interviewing the parents, Oprah would do a full week dedicated to the rape and murder and Geraldo would be on the tube screaming that he would kick the accused troops but.
We would never hear the end of it. An event such as then one portrayed in the movie would have made Abu Ghraib look like a Fox News Alert on Britney's new form of birth control. The MSM would never let us forget.
Therefore, the event never did occur.
