The Feds, after a good number of major FAILS, were finally able to get enough insider information on the MAFIA to bring off a successful prosecution with RICO's far-reaching implications to grab money, assets and send wholesale numbers of the crime families to prison for long sentences.
The problem with the Feds, thus far, is that they haven't figured out how to infiltrate the ultra-paranoid COS (Crimewave of Scientology). In the Mafiia's case, they finally placed (in addition to WIRETAPS) bugs in strategic locations. It was extremely difficult. Then they used those wiretaps to TURN Sammy The Bull Gravano vs the boss. Sammy heard with his own ears the tapes where crime boss John Gotti (his best friend and "loyal" mafia co-conspirator) to trash talk him so thoroughly that Gravano knew it was just a matter of time before Gotti would have him murdered.
That's what the Feds are missing. The incriminating evidence in order to get "loyal officers" to start FLIPPING and ratting out Miscavige. Maybe a few of the top echelon insiders like Jenny Linson & Yaeger, plus some of the PIs they have used for black ops, plus one or two of their dirty-hands attorneys who knows how the money trail works.
In reality, there is NOBODY in Scientology who wouldn't rat out other Scientologists. Scientology Sea Org members are essentially cowards and driven by a palpable fear of what might happen to them if they don't obey authority (COB, RTC, FBI, CIA or any other impressive sounding entity that is "uplines" somewhere).
Scientologists just don't want to be punished by whomever is "uplines" at the moment. That's the sad & hilarious truth about what motivates them sector salvagers. LOL
