"The amazing thing was, I was NEVER told what I was accused of. It was only said that I'd done horrible things, that I'd committed crimes and I should know what they are!"
The reason you don't know what they are is because they are not crimes from a normal human beings viewpoint.
It could be they were merely operating on Hubbard's well-known statements in tech/policy that people who criticise Scientology have crimes. They would have had absolute certainty that crimes had been committed because Hubbard says so. The niggly details of what crimes, or real-world evidence, are unimportant in such an insulated society.
