Yes, this is not a movie. But as all too many events over the decades have shown, there is and always has been a significant fraction of those members of intelligence organizations and soldiers who are fully willing to obey unlawful orders. What has also been shown is that the group of "honorable citizens refusing unlawful orders" is not always as large as we need.
