GUANTANAMO BAY NAVAL BASE, Cuba (AP) — Five Guantanamo prisoners charged in the Sept. 11 attacks returned before a military tribunal Monday, forgoing the protests that turned their last appearance into an unruly 13-hour spectacle.

But the apparent cooperation of Khalid Sheikh Mohammed, who has said he masterminded the worst terror attack on U.S. soil, and four codefendants did little to speed up proceedings that have stuck in a legal and political morass for years.

And Mohammed, dressed a white turban and traditional black vest, made clear he still feels a deep disdain for the proceedings, saying "I don't think there is any justice in this court."
