"as an external consultant, I'm not allowed to know some of the
trade secrets in the documents. The internal side of the team needs
to handle the sensitive process information, and be careful about
how that information crosses boundaries when talking to the
external consultants. Unfortunately, the internal team doesn't know
what the secrets are, while I do. I even invented a few of them,
and have my name on some related patents. Nonetheless, I need to
smuggle these trade secrets back into the company, so that the
internal side can handle them. They just have to make sure they
don't accidentally repeat them back to me."
I remember a scandal at Guatanamo Bay - some of the translators working for the defense attorneys had previously been translators for the CIA where they interrogated the very terrorists they now were defending.
The terrorists knew this. The translators knew this. But the defense attorneys weren’t allowed to know.
The terrorists tried to inform their attorneys, but the attorneys weren’t “allowed to know” the identities of the original interrogators identities.
So the clients were refused to cooperate, which made attorneys resign, etc.
