'I expect we will ask for the death penalty,' Holder said. 'They must face the ultimate justice.' Khalid Shaikh Mohammed, the self-proclaimed mastermind of the attacks on Sept. 11, 2001, and four other top alleged conspirators have been held for years in secret detention camps overseas, and, most recently, at Guantanamo Bay prison in Cuba. After a year of internal debate, Holder said the Obama administration decided they can be tried in a civilian court under American criminal law. 'I have every confidence we can hold these trials safely in New York,' Holder said. Republican lawmakers on Capitol Hill were quick to criticize the decision. Bringing 'the 9/11 conspirators to the U.S. to stand trial could endanger the American people,' said Rep. Lamar Smith of Texas, the ranking Republican on the House Judiciary Committee. Bringing them to the United States 'expands their constitutional rights and could result in shorter sentences,' he added. But the American Civil Liberties Union called the move a 'major victory for due process and the rule of law.' 'We can now finally achieve the real and reliable justice that Americans deserve,' said Anthony Romero, ACLU executive director. In addition, Holder said the men accused of carrying out the 2000 attack on the U.S. destroyer Cole in Yemen will be tried in a military court. The attorney general said that because that crime took place overseas and involved a military target, the military's legal venue was more appropriate. But Holder said it made more sense to try the accused 9/11 plotters in New York, where civilians were targeted. 'Cases are typically tried in the place where the offense occurred,' he said. One complication for prosecutors, however, is that Mohammed has been waterboarded while in custody, and any information he disclosed during these sessions almost certainly will be barred from his trial. The others due to be tried in New York include Ramzi Binalshibh, accused of wiring money from Europe to the men who carried out the 9/11 hijackings. Two planes struck the World Trade Center in New York, a third crashed into the Pentagon in Virginia and the fourth crashed in a field in Pennsylvania.
