Saudi Mustafa al Hawsawi appears at his arraignment as an accused 9/11 co-conspirator in this courtroom sketch reviewed and approved for release by a U.S. military security official, at Guantanamo Bay Navy Base, Cuba, May 5, 2012. The arraignment of five Guantanamo prisoners accused of plotting the September 11 attacks got off to a chaotic start on Saturday when all the defendants defiantly refused to answer the judge's questions and one made outbursts in court.
