Or, better yet, capped him "accidentally" while taking him into custody. Him being this douche, Muqtada al-Sadr, the dunce-cap who never got his degree.
Wikipedia says: "As Muqtada al-Sadr lacks the religious education and degrees required by Shia doctrines, he does not claim the title of mujtahid (the equivalent of a senior religious scholar) or the authority to issue fatwas (religious edicts), consequently he bases his religious authority on his lineage alone."
Put this clown away, once and for all! Make it look like an accident, or don't, I doubt if it matters much.
