President Bush and former Secretary of State Collin Powell told the world that Saddam Hussein had weapons of mass destruction, including mobile factories for germ warfare. When it turned out to be untrue, the CIA blamed an informant. Now, the man code-named Curveball has gone public, claiming he's not a liar. Today's Los Angeles Times reveals that he is Rafid Ahmed Alwan, who fled his native Iraq to avoid arrest. Applying for asylum in Germany, he told the German intelligence service he'd run a secret Iraqi program to produce biological weapons.
