According to Sam at the Iraqi blog Hammorabi, Muqi is having a hard time with the law:
The Iraqi police conducting a big search this morning for weapons! Grand Iyat Allah Sayid Ali Sistani asked that his house should be the first to be searched.I wonder if this is a true story. Of course, if Saddam hadn't killed Muqi's pops a few years ago, the worthless lump of shit might not be such a problem for us today.
The IP then started with the house of Sistani followed by the nearby area before going from house to house in the other regions.
When they arrived to Muqtada Sadr house the guards prevented them from entering. The guards took positions over the roof with their RPG7 and Kalashnikovs.
Muqtada Sadr then went to Sistani to complain about it and to refuse the search but Mr Ali Sistani told him that all the Iraqis should be under the law and the IP indeed started with his house!
