For nearly the entire summer of 2002, Abu Zubaydah was kept in isolation. That was valuable lost time, and that doesn't square with claims about the "ticking bomb scenarios" that were the basis for America's enhanced interrogation program, or with the commitment to getting life-saving, actionable intelligence from valuable detainees. The techniques were justified by those who said Zubaydah "stopped all cooperation" around the time my fellow FBI agent and I left. If Zubaydah was in isolation the whole time, that's not really a surprise.
