Hutu Rwandan genocidal leaders are on trial at the International Criminal Tribunal for Rwanda, in the Rwandan National Court system, and, most recently, through the informal Gacaca programme. Recent reports highlight a number of reprisal killings of survivors for giving evidence at Gacaca. These Gacaca trials are overseen by the government established National Unity and Reconciliation Commission. "Gacaca" is a traditional adjudication mechanism at the "umudugudu" (village) level, whereby members of the community elect elders to serve as judges, and the entire community is present for the case. This system was modified to try lower-level "génocidaires", those who had killed or stolen but did not organize massacres. Prisoners, dressed in pink, stand trial before members of their community. Judges accord sentences, which vary widely, from returning to prison, to paying back the cost of goods stolen, to working in the fields of families of victims. "Gacaca" officially concluded in June 2012. For many, "gacaca" has been a vehicle for closure, and prisoners' testimonies have helped many families locate victims. "Gacaca" takes place once a week in the morning in every village across Rwanda, and is compulsory.
