The UN also found the AUC in violation of various aspects of international humanitarian law, including using civilians as human shields, failing to protect civilians from the effects of their military operations, and for causing massive forced displacement of civilian populations in the region due to their acts, threats and combat operations in the area. Given reports of theft by the AUC of goods, equipment and vehicles belonging to local residents, the UN also found the AUC guilty of pillage (a violation of Article 17 of Protocol II).
