So does anyone know what the story is with this book and/or this "Frankie" guy (perhaps "Angel Garcia")? Does anyone know if the book's publication is now, or will become, a problem for the org? If nothing else, it bears watching.
I know nothing about it. However, what you explain may be true, but I think the facts have to be proven. First, is the book a memoir, and autobiography, fiction, a biographic story from the point of view of an outsider about another person? Then, is it verifiable that the person was in fact a JW, became a JW, stayed a JW, that is, what kind of connection if any exist(s/ed) between that person and the WT? Also, was the person's claims about the crimes committed verifiable? And if such relationship with the WT is verified that exist(s/ed), what if anything did the WT (a) know about it, and then (b) do about it?
With the information that you provide it's difficult to hold the WT responsible of anything related to a person that may or may not exist, that may or may not have committed crimes, and may and may not have had a connection with the WT.
I think that makes an interesting research project, thought.
