Duch, the personification of one of the great mass murders of the last century, seemed to shrink into his chair as he faced a panel of five red-robed judges and a tribunal filled with prosecutors, lawyers and clerks.  A frail, big-eyed man in a white polo shirt, he leaned forward, he leaned back, he put on and removed his glasses. His eyes darted around the courtroom. Invited to address the court, he rose with his palms together in a gesture of respect and pleading, raising and lowering them in front of his face.  “I lodged the appeal,” he began, and was stopped by the command of a judge: “Please speak loudly!”  “The reason I lodged the appeal,” he said again, “is because I have been detained without trial for 8 years, 6 months and 10 days already.”  This detention, most of it in a military jail before the special tribunal was created last year with the assistance of the United Nations, was the basis for the assertion by his lawyer, Kar Savuth, that his human rights had been violated, “even if he was not beaten or tortured.”  A ripple of laughter ran through the Cambodian spectators, who were watching the proceedings on giant screens in an auditorium next to the cramped pretrial chamber.  “This is Cambodian style, they laugh,” said Kek Galabru, the founder of Licadho, a local human rights group. “It’s too much for them because they know that when he was torturing Cambodians there was no talk about the human rights of the victims. Even me, when I hear that, I laugh.”  At least 14,000 people were tortured under Duch’s orders at Tuol Sleng prison, also known as S-21, and sent to the killing fields. Only a handful are known to have survived.  “Under his authority, countless abuses were committed, including mass murder, arbitrary detention and torture,” said a judge, reading the indictment to the court.  He listed methods of torture that included beating, stabbing, suspension from ropes, removal of fingernails and submersion in pits filled with water.  Converted in 1996 by American evangelical missionaries, Duch has become a born-again Christian, apparently ready to confess his sins. When he was discovered in 1999 by journalists he admitted at length to ordering and taking part in atrocities. Comparing himself to St. Paul, he told the journalists, “After my experience in life I decided I must give my spirit to God.”  When the trials begin, his testimony could be damaging to some of his fellow defendants.  A former mathematics teacher, Duch brought the strictness and efficiency of a schoolroom to his prison in a former high school in the center of Phnom Penh, the capital.  “He was strong,” a former Tuol Sleng guard, Him Huy, told David Chandler in “Voices from S-21: Terror and History in Pol Pot’s Secret Prison” (University of California Press, 1999). “He was clear. He would do what he said.”  When asked what kind of man Duch was, another guard told Mr. Chandler, “Ha! What kind of man? He was beyond reason.” The guard said he was most horrified by Duch’s decision to allow two of his brothers-in-law to be brought to the prison and put to death.  “Duch never killed anyone himself,” the former guard said, but he occasionally drove out to the Choeung Ek killing field to observe the executions.  The hearing on Tuesday came one day after the arrest of the former Khmer Rouge president, Khieu Samphan, 76. He was the last of the five initial defendants sought by prosecutors. Taken by the police from a hospital where he was recovering from what was thought to be a stroke, he was charged with war crimes and crimes against humanity.  Two other defendants were arrested last Wednesday: the former foreign minister Ieng Sary, 82, and his wife, Ieng Thirith, 75, a fellow member of the Khmer Rouge central committee.  The fifth defendant, Nuon Chea, 82, the movement’s chief ideologue, was arrested in September. He had been living quietly next door to Mr. Khieu Samphan in a former Khmer Rouge stronghold where most of their neighbors were also former members of the Khmer Rouge.  All of these defendants have complained of medical ailments, and through the years of delays fears have grown that some might die before being brought to justice. The top Khmer Rouge leader, Pol Pot, died in 1998.  In his interview in 1999 with the journalists Nic Dunlop and Nate Thayer, Duch gave what could be a preview of some of his testimony in the trial.  Confirming the authenticity of documents recovered in Tuol Sleng, he pointed out notations made by his superiors.  “This is the handwriting of Nuon Chea,” he said. “You see his handwriting is square. Mine is more oval.”  He admitted his own part in the atrocities but said that he had acted under direct orders and that the entire leadership had been aware of the killings.  “The decisions to kill were made not by one man, not just Pol Pot, but the entire central committee,” he said.
