It's very interesting. I have always thought that McCoy could be Cooper. There are a lot of similarities in his case and Cooper's. I am not looking to get into a debate about Cooper being McCoy, but it does make me wonder if witnesses have seen Cooper and didn't recognise him...
I think the real key elements with McCoy are:
1. His whereabouts on November 24, 1971
2. Why was he in Las Vegas on November 22, 1971.
3. Why did he call his family collect on T-Day night at 10 pm from Las Vegas.
4. Why was he in Las Vegas in early November for an over-nighter.
5. Where did he get the money to buy 6K worth of airplane tix to take his whole family back to NC in December?
6. Why did Seattle refute Calame's claims of evidence.
7. Where is Calame's evidence?
All gambling? All Sin City related? Or something else. Calame is bs-ing? A SAC, really?
