(It has now come out that the US military actually printed up broadsheets announcing that Muqtada had been killed resisting arrest, and that some GI's jumped the gun and actually put some of those out in early April even though in fact, Muqtada eluded his American would-be murderers.)
Paul Bremer's recent attempt to ensure that the major Sadrist leaders are not allowed to run for parliament has the same goal. The civilians in the Department of Defense such as Rumsfeld and Wolfowitz probably went to war against Iraq in part precisely to get bases there. The realization that they might be tossed out at the instance of a few million Shiite slum dwellers has so infuriated them that they attacked the movement without provocation, killed about a thousand of them, and are now trying to disenfranchise several million Iraqis by disallowing Sadrists from holding office.
