As much as I'm not a fan of the way the US has handled any of this, I don't begrudge them the opportunity to make it as clear as possible to the Iraqi people that Saddam is no longer on the loose.
If they're gonna (continue to) flout international accords on the handling of prisoners, then I'm willing to concede that, this time at least, it's been done with the best of intentions - namely reassuring the Iraqi people.
