More on Blackwater: "no evidence the security contractors were fired upon"

An investigation of the September 16 Blackwater shootings has found no evidence that the "enemy" fired at the American elite private guard firm. The unnamed source told CNN.com that the report, conducted by the first U.S. soldiers to arrive at the scene, says the firm also fired at cars that were trying to flee Nusoor Square in Baghdad amidst the gun-fire.
