Bolivian courts made some progress in clarifying responsibilities for human rights abuses in 2011, including convicting seven high-ranking military officers and politicians for deaths in the 2003 street protests. However, lack of accountability remains a serious problem. The fate of scores who "disappeared" before democracy was re-established in 1982 has still not been clarified, and trials of those responsible for killings during marches and demonstrations in recent years have been subject to long delays. The insistence of military courts on trying military accused of abuses continues to be an obstacle.
