Back in the 1980s I found a copy for some friends of mine who were investigative journalists. It was hard to do because Scientology was buying up every copy that they could get to keep the book out of circulation.
I believe it. The church was once very aggressive about hiding their secrets and protecting their manicured public image.
It's funny how that aggression finally backfired on them, as they lost the battle to hide their dirty deeds.
They were once famous for litigating their critics into the ground. Now they just post asinine smear pages on their biggest critics.
