I can say that when I first started having serious doubts and concerns over the WT Organization, I personally went to the local public library in hopes of finding CoC to read and was disheartened that they didn't have it avaiable. I even checked with the other public libraries in surrounding counties via their in-house electronic card catalogue and none of them had it. (you can have a book sent to your local library from one of the other counties if they have it available)
To this day I haven't read CoC but have read many excerpts from it and admire Ray for his courage in writing it.
Some may wonder why I still haven't purchased a copy or borrowed it to read, but at this point in my life I'm already mentally and physically out of the WT so don't really feel a need to.
But I do feel that years ago when I was first looking for it at the library, it would have been such a tremendous help for me at that time due to the passages I've read from it.
It is still on my to do list (to read) one day if I don't run out of time in this life. :)
I owe it to Ray Franz for giving me one of my first probing questions when I was younger about why would anyone ever leave or be DF from the GB.
