From your post:
Mr Al-Mudafer was just six years old when Saddam, with the Ba'ath party behind him, took power. Growing up in Basra, he remembers the time when, on the last day of the Muslim holy month Ramadan, Ba'ath party agents gave his aunt the death certificate of his uncle, and then asked her to pay for the bullet.From FR Patriot Rally Action Report, March 2003
She went into her rant about Bush being evil again. I stopped her and asked her how come she was supporting a mass murderer (Saddam). I told her about Aziz Al-Taee's cousin who was cut into little pieces, delivered to his house in a bag, and the family was presented with a bill for the bullets. If the family complained, someone else would be shot.
Hmmmm... So now we have two different people telling essentially the same story. But like you said, it may just have been standard operating procedure for Saddam.
