I don't believe that many Iraqi people will care a great deal about Saddam's execution. Most of the people have to many problems to deal with already.
What I don't really get is how justice will be provided for the thousands of people Saddam had executed by executing the executioner.
Obviously most of the people Saddam executed were relatively innocent, but does it really make a good example to show the Iraqi people that saddam's executions were so bad that in retalliation we will set the new example- further execution?
