repated reports of shootings of Iraqi civilians by Blackwater

Despite repeated reports of shootings of Iraqi civilians by Blackwater and other U.S. private security contractors, the incidents were "rarely" the subjects of full investigations, current and former State Department officials tell the Blotter on ABCNews.com. "We get almost weekly reports of such shootings, but it is close to impossible to go the crime scene and interview witnesses," said one current State Department official formerly based in Baghdad.
