The reentry of sentenced perpetrators of atrocity crimes is part and parcel of the pursuit of international and transitional justice. As men and women sentenced for war crimes, crimes against humanity and genocide by the International Criminal Tribunal for the former Yugoslavia (ICTY) and the other tribunals return from prisons into society and communities questions arise as to the impact their reentry has on deeply divided postconflict societies, in particular on victim groups. Contemporary international tribunals and courts mostly do not have penal or correctional policies of their own, and the legacy of early release, commuting of sentences and amnesties that Nuremberg and other post-World War II tribunals have left, is a particularly problematic one. Germany’s historical experience provides an analytic blueprint for understanding in which ways contemporary perpetrators return into changed and still fragile societies. This comparative analysis between Nuremberg and the ICTY is based on two data sets including information on returning war criminals sentenced in both tribunals. The comparative analysis focuses on four themes: politics of reentry, admission of guilt and justification, memoirs, and political activism.
