Let me get one thing clear: I detest Saddam Hussein. He was a disgusting human being and a tyrant. I cheered with everyone else when he was finally captured by US troops. That said, even I have to admit that Saddam Hussein did not receive a fair trial.
The Saddam trial was a sham, in violation of many international laws and agreements, intended to appease the Iraqi people who are trying to build a peaceful country, along with the Americans who continually question why we are in Iraq (like me). In the end, the trial will have accomplished neither, and it will put another blemish on our handling of international affairs.
Saddam was denied access to a lawyer during his first year in custody. During the trial, three of the lawyers on his defense team were assassinated. Witnesses on his behalf were beaten and received death threats. After his conviction, an appeals court was little more than a quick hearing conducted by the same people who convicted him. The entire trial and appeal was done while Saddam was in US custody, yet the punishment was carried out by Iraq. The legal system used was also Iraq's.
From a legal standpoint, nothing made sense about this trial. The evidence against him for this particular case was actually rather weak, and probably not enough to receive a death penalty if it were under US law. It is against the Geneva Conventions to hand over custody of a prisoner of war to an adversary of that prisoner. Some US officials have claimed that the Iraq government is not Saddam's adversary, because he was once the president of the country. We can't make that claim if we also claim that the old regime is gone and the new government is helping our fight against the old regime. By definition, that makes the new government an adversary.
There were other serious charges against Saddam Hussein that likely would have led to him receiving the death penalty, eventually. Instead, we used a kangaroo court to get a quick verdict and punishment. The outcome may satisfy us, but we can't exactly call it "fair", as President Bush did this week, with a straight face.
