If Ford or BMW sent their drivers to ensure that the car was driven by a suitably drunk person and was targeted to the grandmother and her grandchildren, then, I would think that is not merely a tort, it is a criminal conspiracy to conduct mass murder. IMHO. Willow Run can expand on the legal nicety, but that wouldn't be a tough decision for a member of the jury to come to a conclusion based on the evidence.
You appear to have missed my point, which was a somewhat sarcastic response to this pile of horse apples.
If one of the western supplied weapons were to shoot down a civil airliner, would our western leaders be legally responsible and likely to be prosecuted for supplying the weapon?
