With...private contractors in Iraq facing tighter scrutiny, the House overwhelmingly approved a bill today that would bring all United States government contractors in the Iraq war zone under the jurisdiction of American criminal law... The bill was approved by a 389-to-30 vote, despite strong opposition from the White House. It came as lawmakers and human rights groups are using a Sept. 16 shooting by Blackwater...to highlight the seemingly lawless circumstances in which many contractors have operated... Iraqi officials have said they would like to prosecute the Blackwater case in their courts, but it is extremely unlikely that American authorities would allow them to assert jurisdiction.
