Washington Post: Silence of 4 Terror Probe Suspects Poses Dilemma:

"FBI and Justice Department investigators are increasingly frustrated by the silence of jailed suspected associates of Osama bin Laden's al Qaeda network. [...] Among the alternative strategies under discussion are using drugs or pressure tactics, such as those employed occasionally by Israeli interrogators, to extract information. Another idea is extraditing the suspects to allied countries where security services sometimes employ threats to family members or resort to torture."
