My main concern is the reason RR did what he did. I do not know RR like Conf. so I may be projecting onto him motives that are not his own. But it would appear to me that he is seeking acceptance from someone - he was and has been rejected within the JW religion so he goes somewhere that he can feel "normal" and in turn he does something to get a lot of people's support and admiration. I am sure there are many ex elders here that have the same book? Those are only questions he can answer.
Regardless of the moral issue, the main issue now is making sure RR is ok. It is my understanding that he has a lawyer, however the damage is done. There are post that describe his every move as well as pictures of him. A judicial committee is not a legal one, so they do not have any authority over him. However, a court of law does. So if the owner of the book choses to purpose legal action, he can. If RR starts improperly quoting from the book or not giving the proper cite reference he may get pursued by the WTBTS. Who knows with those guys what their motivation is. As was proven by Elsewhere's site, if they can shut you down they will.
Also, unless RR is copywriting or selling part of the book, reproducing the book with out proper authorization, then the issue is now just one of having possession of it. Yes, the WTBTS can go in on a Motion for Temporary Restraining Order (TRO) and get a Preliminary Injunction (PI) but again, the consequences are not do or die. As long as he does not violate any type of TRO or PI that a court has issued, he will be fine. The JC is just a group of old men who wish they had the power to rule the world. The issue of the book is theft and chancery. If he turns over the book and apologizes (I can hear the screams now) the chancery issue will be most likely be dropped. If a TRO or PI is entered, RR may be stopped from posting or speaking against the WTBTS for a while (depending on how well the JW lawyer argues the issues). He may also be issued a fine if he does not abide by the order entered in the case. I am sure that his lawyer is handling it the best way possible.
I think in the end it would be more harmful for RR to be cut off from the frienships he has formed here and on other sites, because he will really be "cutoff" and that maybe more then he can handle.
I hope the best for him. He should tread carefully as this rises and falls on him and regardless of the "storm the castle walls" that he may get from various people, they are not the ones that will have to deal with the consequences of his actions (and I am not referring to the JC consequences, I am referring to the possible legal actions that could be taken).
RR, LISTEN to your lawyer, you may not want to agree with him/her, but they know the law and want to keep you out of harm's way.
