it makes a mockery of the concept of universal human rights. it doesn't strengthen the rule of law, because there is no sense Saddam got a fair trial. He should have been packed off to Europe, tried in an international court for all of his crimes, then sentenced to life imprisonment. from the USA public relations point of view, it was good to have him executed as quickly as possible, that way there won't be a sustained examination of USA/ CIA support for Saddam's brutality over previous decades.
the nature of his execution was a human rights outrage. the taunting, the men hidden in masks - if what you are doing is the right thing, take the fvcking masks off and show your face, cowards. this is everything that is deplorable in human nature. this is really no better than what Saddam himself did. just another torture-execution in a brutal society that has no respect for human rights.
