I note that one of the sources I found online, which I linked to above, makes the same statement, indicating two sources for its "article," although I'm not sure whether this particular statement is sourced from them. That link, is, again, here. I also note what seems to me to be a possibly dubious logical flaw in the above argument, specifically whether the court case could be the only place in which an individual could be "legally forced" to do anything. I cannot think of any other specific situations in which he might have been "legally forced" to make such a statement, but, I am not an expert in the law regarding such matters either. I believe that if there are serious questions regarding this matter, the better place for such discussion would probably be at the WP:RSN or WP:NPOVN, and also perhaps contact editors at WP:LAW or any editors with legal expertise to see if the possible flaw in the above logic is a real flaw.
