The best case is that it never happens. The second best case is that it’s caught as soon as it happens and stopped then. The third best case is that it’s caught some time after it happens and stopped before it has any external consequences (people getting sick). The fourth best case is that it’s caught some time after it happens but only stopped after external consequences.

Etcetera etcetera. Throw in another dimension of punishment besides just stopping operations and it gets more complex. With a little imagination, the worst cases are much worse than any of the above. We can be dissatisfied with the actual circumstances but still recognize the nuanced factors which might make up a “working” system.
