I understand war crimes and the Geneva Convention. I still don't understand your point in highlighting my post that at least the soldiers were dead before they were mutilated. I would think that would bring at least some small measure of comfort to any family member to know that they weren't tortured while alive.
If 30 gunmen opened fire on those soldiers, it's unlikely they were alive while tortured.
It seems to me that in order to be tortured, one must be alive. If you are dead, it is mutilation, or some other word to describe what they might do to a body. At any rate, one can hope they are still alive and recoverable.
