Somewhere in the old BOFH stories, he goes on vacation and decides to make sure his job is secure. So he remotely drops a network switch, takes the panicked out-of-hours call, and insightfully "diagnoses" the problem. That's the sort of thing you really don't want to encourage. If nothing else, doing thorough post-mortems can help create a company where allowing fires to grow isn't rewarded.
