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.
