It does not matter that they were stochastic events because the reason we have regulation and procedures and protocols for these systems is to reduce randomness and mistakes as close to zero.

While individually each event can maybe just be random mistake having two could be the beginning of some new information about the system(s) we have to consider.

So we should all say and act like this is not acceptable and we need more focus on making these stochastic events not happen now that they are not just a mere probability over an event space filled with randomness. They just happened.
