How can you tell that's a mole? That could be anything from a rash to a bug bite. He was living underground and all.
They did DNA testing to see if it was him before they announced the capture, and it turned out to be positive. I know Saddam had dopplegangers, but I really don't believe he had clones.
Of course, I'm sure there will be people saying that the evil US could have fudged the DNA testing which is why I'm hoping the US allows other countries that have opposed us to conduct their own DNA tests on him to make sure and prove it's him.
For example, if France does an DNA test on him and agrees it's Saddam, then I think we can all agree it's not some big bad Bush hoax.
