In the wake of Prince's testimony before Congress, the US House passed the Military Extraterritorial Jurisdiction Act in October 2007 that subsequently led to the prosecution by U.S. courts of some US military contractors, but only for incidents involving attacks on US nationals. The legal status of Blackwater and other security firms in Iraq was a subject of contention. Two days before he left Iraq, L. Paul Bremer signed "Order 17" giving all Americans associated with the CPA and the American government immunity from Iraqi law. A July 2007 report from the American Congressional Research Service indicates that the Iraqi government still has no authority over private security firms contracted by the U.S. government. On October 5, 2007, the State Department announced new rules for Blackwater's armed guards operating in Iraq. Under the new guidelines, State Department security agents will accompany all Blackwater units operating in and around Baghdad. The State Department will also install video surveillance equipment in all Blackwater armored vehicles, and will keep recordings of all radio communications between Blackwater convoys in Iraq and the military and civilian agencies that supervise their activities.
