Weird situation all around...
I understand why the US did it. They saw immediate skepticism and wanted to prove to the Iraqis that Odai and Qusai (or however the hell you want to spell their names) were dead.
I don't mind seeing the pictures of dead people...but given the Geneva Convention, it shouldn't have been done in this case. But the Bush administration will probably mention something about "illegal combatants," tell us that the discussion is over (like your mom or dad might have done to you back in the day), and then it disappears.
The US has pretty much proved that it will do what it has to do. The Bush administration said they would come over and remove Saddam...and voila! (more or less) But the US seems to be simply unbelievable...untrustable...for a combination of reasons.
Bottom line: No win situation for the US...they should have just said, "They're dead, now shut the fuck up before we send your civilization back 25,000 more years."
