Not sure what you insinuate was stolen, I'm not familiar with O'Donnell
Letters and statements of facts (eg. finance records) don't have copyright associated with them in the way that a book or literary work does. Likewise if certain documents are filed in a lawsuit, these become public domain.
If someone makes a copy for example of a list of sex offenders, there is no copyright on it. Moreover, you cannot claim copyright or ownership over something you did in the commission of a crime, if you steal a car, it does not become yours, if you make a book about all the murder you committed, you cannot claim copyright if it is in fact a statement of facts.
If WTBTS claims copyright, then it admits that it has authored those documents, which is why they don't claim copyright on for example, the elder manual but they do on for example any other publication they have ever made. If you make a verbatim copy of, for example, their website, they have the right to sue, there are exceptions off course if you use excerpts for commentary, satire etc.
Unless someone physically stole a document (eg. an embossed and notarized document that has some value - such as the deed to the Kingdom Hall) AND unless he was aware the document he received was physically stolen, he did not 'receive stolen goods'.
Confidential property does not exist, there is real property and there is imaginary (intellectual) property, you cannot 'steal' a movie for example unless you go physically steal a DVD from the store or a reel from the movie studio and then it's not copyright infringement, just larceny or theft. Vice versa, you cannot steal a car by making a replica of it, at best, you committed an intellectual property violation.
