Rhetorically speaking, the architecture is (1) "what we are doing is correct beyond doubt or question" (2) "therefore an explanation for the way we are doing it is a courtesy and a privilege." This is the fundamental difference between an open society and a closed society: the open society requires the government to act with consensus or else the government is replaced. The closed society is compelled by the government so the consensus is achieved by definition. It's not "prisoners or your children you pick" it's "the Nazis are so depraved and worthy of genocide that even our hardened prisoners wish to take part in this historic, patriotic action."
