That's very interesting. I'd like to know the distance from this car to the Bradley vehicle that hit it with machine gun fire. If the Bradley was firing from fairly close range...say 70 meters or less, then I think the gunner would have been able to confine his fire to the front end of the car and not hit anyone in the passenger compartment. The Bradley has a 7.62 mm machine gun with a high-quality sight and the vehicle was proably standing still at the time, so the gunner should have been able to take only accurate shots at the engine block area. This case is looking more suspicious all the time. I wonder if someone inside the car grabbed the agents gun and shot him either accidentally or intentionally. This could be an Italian "friendly fire" accident.
Now there's a plausible theory...accidental shooting by a colleague and he collapses, covering the (sic) journalist.
