I would go out on a limb and say, "No." There probably is not a molester on the GB. They probably are all lily-white squeaky clean men. But there are pedophiles somewhere down the chain of leadership and there has been at least one molester in the Ivory Tower in the past.
Plus, as a cult that never admits wrong, Watchtower must keep protecting what they can about the way they have done things. The 2-witness rule is supposedly "from the Bible" and universal to all things JW. They cannot bring themselves to make exceptions.
Their way out is simple- make criminal and congregational things separate. Just because you can't disfellowship someone without 2 witnesses doesn't mean you can't "mark" them after you have cooperated with the law and the law has found them guilty. It doesn't mean you can't stand by a child when they make an accusation even if you can't prove that they are telling the truth. But they see any bending as making exceptions and maybe they, as a dictatorship cult, are right.
