How in blazes would soldiers who were manning a checkpoint in the middle of bum-f*ck Iraq, in the middle of the night, possibly know that the passengers in the vehicle which was speeding toward them, and ignoring major league signals to stop (gunfire, etc.) were "Europeans, journalists, Italians, Communists and terrorist sympathizers"? Think about what you are posting.
A.Pole doesn't have a brain. Not one that works anyway. If it was known who was in that car, US forces would have wanted her alive to find out all she knew about her contact with the terrorists, where she was held, etc. To kill someone with potentially useful information just because of she was an Italian or a commie is absurd to the n-th degree.
