This is obviously a controversial subject, Saddam did commit crimes but we have to point out that many others have done as bad or worse than him and still have avoided trial.
Any how whether one considers that he should have been hanged or not, he must be respected after death for he was amongst other things a nationalist.
I just find this exibition discusting: A work titled Shark of David Cerrny was exhibited last year in Middelkerke (Belgium). In it appears a figure that represents a submerged Saddam Hussein, as if it he was a shark, in a fishbowl wih his hands and feet tied, and with a cord to the neck.
