A former hostage and CIA was just on "Fox and Friends". He was saying it was the guy you have marked out, not the one that is circled.
It sounds like there is a lot of evidence that the new president was involved in the planning of the storming of the Embassy, but I don't think he's been in any of the photos I've seen. The new president is a pretty short guy too.
I trust the hostages "can" identify there captors. 400+ days makes an impression.
