Church of Scientology paid two private investigators millions to trail David Miscavige's rival, lawsuit claims - 2012-09-21

Church of Scientology leader David Miscavige ordered surveillance on one of his former church rivals in a secret operation that lasted 25 years and ate up millions in church funds, a Texas lawsuit alleges.
The two private investigators who filed the suit say the church hired them to conduct intensive surveillance on Pat Broeker, a church leader who worked closely with Scientology founder L. Ron Hubbard in the 1970s and '80s. Broeker was ousted by Miscavige in a power struggle after Hubbard's 1986 death.
