One of the hostages has fingered the guy we circled.
That's not worth much after 25 years. As I said, there are at least three guys in that photo of Rosen being escorted who look similar to Ahmadinejad. Everyone now agrees that the first one we fingered as Ahmadinejad is in fact not him, based on the nose-hump and earlobes. That should inspire a little caution in these ID's.
