I don't remember anything being said about the KM announcement. I would have only been 13 and didn't know any of the names of anybody on the Governing Body except for Knorr. Maybe there was whispering, but I didn't pay attention. But when the Times article broke, I remember photocopies being passed around the hall. That created quite a stir. Him leaving the GB could have been for anything. Health, family, who knows? But the Times article showed that he had disagreements about the religion.
I remember thinking the GB practically talked to God himself. If this guy could leave, what did he know? I don't remember exactly when I heard he had a book. I thought I might have heard about it mid-80's and had looked for it. I do know that I was watching a Christian show on TV where they were talking about JWs and one guy on the panel was selling CoC. I ordered immediately.
Acutally my local Barnes and Noble bookstore had it in stock... but in spanish. I told the girl I needed english, so she had to order it. It was hilarious. I live in Florida and in a predominately english area, not south florida where there are more spanish speaking people... but they had the book in spanish.
It's been being translated into other languages. So, the spanish version might be "new" and is more likely to end up in a bookstore.
