Mexican security forces have committed widespread human rights violations in efforts to combat powerful organized crime groups, including extrajudicial killings, disappearances, and torture. Almost none of these abuses are adequately investigated, exacerbating a climate of violence and impunity in many parts of the country. Criminal groups as well as members of security forces continue to threaten or attack human rights defenders and journalists. Although Mexico’s Supreme Court found the use of military jurisdiction to prosecute human rights violations was unconstitutional, virtually all alleged abuses by military personnel continue to be prosecuted in military courts.
