The civil rights advocacy group, Human Rights First (known formerly as the Lawyers' Committee for International Human Rights), has recently released a report on using coerced evidence to prosecute terror suspects.  The report, written by Deborah Colson and Avi Cover, analyzes the relevant cases and offers a critique of interrogation practices.  Colson and Cover also present the social science research on the effectiveness of "coerced" interrogation and whether it produces trustworthy information.  The report is available in full-text PDF format here.
