In any organisation things will go wrong at times, for all sort of reasons: software bugs, human error, organisational dysfunction, malicious actors, whatever.

In any organisation things will go wrong at times, for all sort of reasons: software bugs, human error, organisational dysfunction, malicious actors, whatever. Mistakes get made. And even if the original mistake was hugely egregious, it's usually not a huge problem if you actually deal with it well (barring things like medical errors, but even there, trying to cover up a mistake can cause more harm than the initial mistake, at least in some cases). For these kind of institutional problems most of the time it's really the response to the mistake that turns a mistake in to a huge catastrofuck.
