Well, the Mormon church has only itself to blame on this one...for the above reasons, there's a "slew" of ex-Lds missionaries who were recruited by (& eventually landed with) the CIA. Hence, Russians have made the connection.
The missionaries in the field aren't working for the CIA during their mission service.
(Of course they aren't; but just to toss out #s...let's say 1 in 10 Lds missionaries in Russia eventually lands with the CIA...the Russians know that this "10%" is accumulating info that will one day be utilized by the CIA)
They have knowledge of what Howard Hughes life was like, while being surrounded by MORMONs!
