In the long drop hanging (like this one) the broken neck is also accompanied by a separation of the spinal chord, at the C-1--C-4 level, from the brain, which results in immediate unconsciousness. From that moment on, asphyxiation finishes the victim.
The video's angle makes it appear as if Saddam is horizontal (i.e., on the ground) but, if you watch is closely over and over, you'll see he is still suspended by the rope around his neck.
He's dead.
In the long drop hanging (like this one) the broken neck is also accompanied by a separation of the spinal chord, at the C-1--C-4 level, from the brain, which results in immediate unconsciousness. From that moment on, asphyxiation finishes the victim. And the executioners put a plastic sleeve over the knot, with a large flange against the head, to amplify the torsion and thus ensure the spinal chord was severed. That is absolutely lethal, with or without asphyxiation.
