There’s not a single word about “Scientology” in the article I linked to, so who are you shilling for? There also is no “theory” there at all: the facts are fully documented.
Izzat you, Liddy?
The article plugs his book "Watergate: The Hoax". Its premise is that the Watergate break in was a CIA cover up for the burglars attempting to assassinate L Ron Hubbard in Morocco a a week earlier because his mental powers were a threat to them. Maybe even replacing him with a double who did his job so well no one noticed or was too afraid to say anything until this book was published (available at Amazon in paperback and Kindle).
This is your brain on L. Ron Hubbard: Watergate, Scientology, and late-night radio spells out the problems of the book well enough.
