It must be very disconcerting to have only a so-called ''elite'' discuss thing at the very top only to have moments later discussed by everyone on websites. I'm sure only a handful of people know about the letter before anyone like CO's or Zone Overseers know.
Like someone said earlier, they could make some phony ''leaked'' letters in kind of a ruse in attempt to narrow down who may be leaking things. Doubt that would work though, it would just create more paranoia, or create confusion.
