This is probably why:

"Two key members of al-Sadr's political and military organization were gunned down last week, the latest of as many as seven key figures in the al-Sadr organization killed or captured in the past two months."

"The deaths and captures came after al-Maliki, also a Shiite, dropped his protection for the organization."

Apparently that was another part of the extra 20,000 troops that wasn't mentioned much in the media. That this guy was gonna lose his protection and it would be open season on his militia. I believe he is the fuck stick that has the posters of destroyed u.s. humvees all over Iraq.

He looks like a devil worshiper. Bah, who am I kidding- all the muslim clerics look like they pay homage to satan.
