The Church of Scientology was devastated by the Internet. Throughout the 1970s and 80s, they were successful because they were able to control public perception. They promise wonderful things, and in 1985, if you wanted to learn more about the CoS, you didn't have many resources. If you found any books on the subject, it's likely they were written by the CoS. If anyone wrote anything negative, it rarely got published, because the CoS had an army of lawyers ready to sue people into the ground.
Now, if you Google "Church of Scientology," it's easy to learn how destructive the organization is.
Back in 1996, SPY Magazine published a story titled "Do You Want to Buy a Bridge." It was written by Mark Ebner, who knowingly "infiltrated" the lower levels of Scientology, documenting every step of the way. His writing style will make you laugh occasionally - but don't forget - this is a seriously dangerous organization.
