And he knows about revolting

But only as a "second step."

"Shiite cleric Sadr calls for 'civil revolt' in Iraq," from [1] Gulfnews (thanks to Sr. Soph):

Najaf: Shiite cleric Moqtada Al Sadr called on Iraqis to stage sit-ins and threatened a countrywide "civil revolt" if attacks by US and Iraqi security forces continue against his followers.

In a statement read out by senior aide Hazem Al Araji, Sadr said, "We call upon all Iraqis to stage sit-ins all over Iraq as a first step. And if the people's demands are not respected by the Iraqi government, the second step will be to declare civil revolt in Baghdad and all other provinces."

He also threatened a "third step", but said it was too early to announce what that would be.

Hmmm, now what could it be...
