Katie almost certainly has all the dirt she needs to bring down both Tom and Scientology. The "close" relationship between Tom Cruise and Scientology head David Miscavige is the stuff of talk among Scientologists and ex-Scientologists. For example, from the deposition of Andre Tabayoyon who was in charge of security for Scientology headquarters:
During the 1980's, Miscavige befriended the actor Tom Cruise and they spend a lot of time together on the Hemet base. Their special chef, Sinar Parman, would prepare them fancy meals. Often they would hang out alone in the space designated for L. Ron Hubbard on the Clipper Ship we built in the desert. This space had a small kitchen, a little dining room, a little bar and a bed.
Ummmm ....
Unclear on the concept?
