How much of a role did the requirement for complete secrecy play in this scenario? Secrecy mean the recipients of such orders were isolated, thinking they were by themselves in this. Such a person will be much less likely to disobey orders. Now that the dam has sprung a leak, and the full extent is becoming evident, people will begin to realise that they are not alone, and it is safe to talk. There is safety in numbers. One gets the feeling that the whole scheme is unravelling, and this is the trickle before the dam bursts. I'm looking forward to it.
