Aid to a Colombian Air Force unit that has been involved with a number of war crimes including destroying part of a village called Santo Domingo during an encounter with the Revolutionary Armed Forces of Colombia (FARC) in which 18 civilians died, has been suspended. The Colombian government tried to cover up the incident, blaming it on a FARC car bomb, until shrapnel from US-made ordinance was discovered and the helicopter pilots involved confessed that they had received targeting information from AirScan a contractor working for the US Air Force. José Miguel Vivanco, Executive Director of the Americas Division of Human Rights Watch, said “When there is impunity in Colombia, as in the Santo Domingo case, it is imperative that the Department of State follow its legal obligation to send precisely this kind of clear message. This decision strengthens the credibility of the policy and the rule of law...It is particularly important for the United States to demand credible investigations when its weaponry and U.S. citizens are implicated in abuses,”
