Idiocy backed into a Corner
It's like this. Some security guy makes an idiot of themselves by making a really stupid decision or saying something outrageous. They won't back down as they'll lose face. The supervisor is called over and as the security guy is their friend and colleague they're unlikely to say the initial action were the actions of a loopy loop. They then defend the action using further dubious excuses and so the chain of idiocy continues right up to the top if necessary.
