9/11 Defendants Stage Protest at Guantanamo Hearing - WSJ.com GUANTANAMO BAY NAVAL BASE, CubaThe self-proclaimed mastermind of the Sept. 11 attacks repeatedly declined to answer a judge's questions Saturday and his co-defendants knelt in prayer in what appeared to be a concerted protest against the military proceedings. Khalid Sheikh Mohammed and four other men appeared for the first time in more than three years for arraignment at a military tribunal at Guantanamo Bay. They are charged with 2,976 counts of murder for the 2001 attacks. The hearing quickly got bogged down before they could be arraigned. Mr. Mohammed and his co-defendants took off the earphones that provide Arabic translations and refused to answer any questions from the judge, Army Col. James Pohl, dramatically slowing a hearing that is heavy on military legal procedure. How long will these trials last?
