One of the witnesses managed to get a mobile phone into the execution chamber, and recorded the entire event, from the time when Saddam is brought into the chamber, his hands and feet shackled, to the moment when his body is hanging lifeless at the end of the rope.
It is shocking, of course. But the most shocking thing about it is the sound.
Far from being a quiet and dignified business, the new video shows that several of the witnesses taunted Saddam during the last seconds of his life, chanted the name of one of his many enemies, and told him he was going to hell.
