As a true follower of the constitution I believe in religous freedom. Scientology however, seems much more like a giant cult. It is based more on works of fiction than fact, and it seems like more people are being brainwashed into it everyday. One could argue that this is similar to religion over the years, but not in any western civilization in recent years.
Families have been broken apart because of Scientology, and people have been left bankrupt. I think the government should investigate into the inner-workings and see if the pose a threat to Americans.
