They've had ample time to train one of his many doubles to give a reasonable performance. He is either dead or he left the country before the 911 attacks and had cosmetic surgery, ergo would be unrecognizable today. He was rumored to have 14 doubles and I think they are the ones who have been spotted thru out this ordeal.
You think a double would pass ethan hunts face recognition software? No double. Spliced and digitized yes (Like I thought the tape with the Sheik was), double no.
Now a double in the best stocks in the stock market - probable. Today was the day. Fear is wrung from the market.
