Can't remember which morning show it was this morning, but they had a guy on comparing photos of the new Iranian leader and the hostage taker the hostages say is him. I'm sorry, but from what I saw, they are not the same person. There were some major and distinct differenes in facial features. From eye seperation, nose shape, ear lob shape, and other features.
I saw something of that, comparison of photos, yesterday, too, and it looked as if only experts could say definitively whether he's the same person or not.
