Now, get this as a technical fact, not a hopeful idea. Every time we have investigated the background of a critic of Scientology, we have found crimes for which that person or group could be imprisoned under existing law. We do not find critics of Scientology who do not have criminal pasts. Over and over we prove this. [...] We are slowly and carefully teaching the unholy a lesson. It is as follows: "We are not a law enforcement agency. BUT we will become interested in the crimes of people who seek to stop us. If you oppose Scientology we promptly look up—and will find and expose your crimes. If you leave us alone we will leave you alone.
