Marty Rathbun is quite a bit more than a "former Scientologist". From his own blog:
I was Tom Cruise’s auditor (Scientology counselor) between 1996 and 2004. I was his liaison to Chairman of Scientology David Miscavige during those same years. I advised on all aspects of Cruise’s 2001 divorce with Nicole Kidman. I set up the initial Scientology indoctrination of Conner (then age 6) and Bela (then age 9), and supervised it subsequently. I was also the senior church official over Scientology Inc’s Office of Special Affairs (the dirty tricks and propaganda arm of Scientology Inc) from its inception in 1982 through 2004.He knows so much about Scientology's intelligence and "dirty tricks" organization because he's the one who set it up and ran it.
