I don’t really think that people in even the most elite SF groups are bullet-proof superhumans. Apart from anything else, this has also put his family at risk from vengeful muslim funadmentalists who might want to strike a blow for the moongod and his paedophile prophet in memory of OBL.
Fox have been very irresponsible here.
His name would have been revealed nomatter what if he wanted to give the story real credibility. Perhaps the team got together and decided the member with the least family to worry about should speak out and set the story straight.
We won't know why he took such a monumental risk until the book is released. But if he is who he says he is, I would trust his judgment.
Also, if this is for real I wouldn't be surprised if the book is suppressed and the entire team is somehow quieted.
