One of the most worrying patterns for me, in both government and any sufficiently large corporation, is the idea of secret rules and dishonor without explanation or appeal.
Yes, and people right here on HN will often defend such rules because "if the rules are known, people might comply with them". The secrecy and ambiguity often are the point as it allows the powerful to attack the weak under the guise of legality.
It's a one of least-resistance solutions to integrity/interpretation problem. Good integrity is expected but most people don't think like programmer-lawyer-surgeons, so it's an impossible goal. Overly strict rules are in fact detrimental in many ways too. Obscuring the rules obscure all those problems.
