The CIA and FBI do have recruitment programs for Mormon graduates, as they value the language skills and their abstinence from alcohol, drugs etc. And while they may be over-represented proportionally, they don't run the show of course. Most of the sources I have seen take the few hard numbers available and do a lot of speculation on the top.
