That's great news.
I would imagine that the Watchtower has its own internal means of discovering the identity of Kevin McFee if they so wished. He uses his voice and I think his child's voice as well. A link to that video, requesting identification, in a newsletter to all elders, would likely give them that information. One benefit of being a united organisation. However, they wouldn't dare link to such a potentially damaging video.
Its funny that the Watchtower also thought they were onto something. They believed that Kevin McFee had obtained their footage illegally and I assume, that by persuing him, they would find the source of the leaks from Bethel. They would have been disappointed to discover that Kevin simply obtained the leaked footage from the John Cedars crew and that he had done nothing illegal. What a waste of time and money it has been for them.
Unfortunately, in their wasted efforts they have targeted a man who the court has proven, they had no cause to. It was their responsibility in the first instance to determine copyright infringement and it clearly was not. They are responsible for the pain and suffering caused to Kevin and should compensate him for this if they consider themselves Christian leaders.
