if this guy is a moslem, then he is still a terrorist. He may be a deep sleeper right now, but his chosen religion commands him to kill non-moslems.
If he’s a Moslem and combating Islamist militancy, then he’s an apostate. Whether the one or the other ultimately wins out remains to be seen. It could be Taqiyya, but there are instances of others doing the same and doing so sincerely.
Think Professor Snape from the Potter series, playing double agent.
As far as I’m concerned, the Green Prince’s conversion to Christianity is suspect. In the book, he says that he baptized himself at the beach by going into the water with his Christian girlfriend, and dunking his head under. He keeps his Islamic name, and makes strange statements on a Christian radio station. So perhaps the Green Prince is practicing Taqiyya, just like Odumbo. On the other hand, maybe not. Same here.
