This report provides the findings of a study of former detainees who were held in U.S. custody in Afghanistan and Guantánamo Bay, Cuba. The primary objective of the study was to record the experiences of these men, assess their treatment in detention, and explore how the conditions of their incarceration affected their subsequent reintegration with their families and communities. Our research reveals serious flaws in the system created by the Bush Administration for the apprehension, detention, interrogation, and release of suspected members of the Taliban and Al Qaeda taken into U.S. custody since the attacks on September 11, 2001. This report was completed in partnership with the Human Rights Law Clinic (Berkeley Law), and the Center for Constitutional Rights.
