Good piece in then LA Times today about CURVEBALL, the Iraqi defector who's reporting on alleged Iraqi biological warfare programs was cited extensively as a key element of the case for war. HUMINT is great when it's factual and accurate, not so much otherwise - the real trick is telling the difference. In this case, the guy seems like a Grade A Loser-Boy.
