Powerful Democrats on Capitol Hill are clamoring for creation of a bipartisan 9/11 style" commission to investigate the legality of the Bush administration's antiterrorism tactics-especially its use of harsh interrogation techniques. The case for a "truth" commission was bolstered by the disclosure this month that the CIA had destroyed 92 videotapes of the interrogations and confinement of Al Qaeda suspects. A dozen showed the use of ... torture. Lawmakers say the obvious model for such an inquiry would be the 9/11 Commission. [But] the commission appears to have ignored obvious clues throughout 2003 and 2004 that its account of the 9/11 plot and Al Qaeda's history relied heavily on information obtained from detainees who had been subjected to torture, or something not far from it. The [Commission] raised no public protest over the CIA's interrogation methods. In fact, the Commission demanded that the CIA carry out new rounds of interrogations in 2004 to get answers to its questions. That has troubling implications for the credibility of the commission's final report. In intelligence circles, testimony obtained through torture is typically discredited; research shows that people will say anything under threat of intense physical pain. Former senator Bob Kerrey of Nebraska, a Democrat on the commission, told me last year he had long feared that the investigation depended too heavily on the accounts of Al Qaeda detainees who were physically coerced into talking. Kerrey said it might take "a permanent 9/11 commission" to end the remaining mysteries of September 11.
