This information often gets lost, suppressed, shadow banned. Try to google for “David Miscavige CIA Cryptome” and you find hundreds of mainstream and CoS and RTC sites, which do not contain any mention of “CIA” or “Cryptome”.
The list of members of AFIO have been leaked:
AFIO is the Association of Former Intelligence Officers: http://www.afio.org
And on this list you find two leading figures in Scientology:
Miscavige, David 6331 Hollywood Blvd, Los Angeles, CA 90028
Jentsch, Heber 6331 Hollywood Boulevard, Los Angeles, CA 90028
