al-Libbi, al-Liby...What's the Difference?

I was watching the Daily Show (as I am wont to religiously do) one day last week when it had on, as guest, Tom Ridge, former Secretary of Hinterland (er, I mean "Homeland") Security. Ridge commented on how this nefarious al-Libbi character, supposed "number 3 man" in Al Qaeda's leadership, had just been captured and Jon Stewart didn't challenge it. He even commented that it was a good thing and I was left thinking, "Wait a minute...we caught the number 3 guy in Al Qaeda? Impossible. BushCo isn't nearly that adept (although, they are just that lucky)". Well, I can't fault Stewart too much for not taking Ridge, or the Bush regime, to task. He is, after all, a fake news commentator. In any case. Here's the challenge to the capture. Turns out it may all be a case of mistaken identity. Oopsie!
