Makes me wonder if sometimes the GB have occasionally been specifically and deliberately not told some things (for whatever reason).
It wouldn’t be difficult…
…after all, they’re surrounded by folks who are never really allowed to disagree with them.
It’s not much of a stretch to think that some of the less-scrupulous (or naive) types might be tempted to use that as a pretext to simply refrain from telling them certain details, even if only to give them “plausible deniability”.
