Did you know that buildings have doors that cannot be locked to prevent them from being opened from inside, because otherwise in case of a fire (or in the US, active shooter), people will die if they cannot exit the building?

Did you know that many industrial plants intentionally disable certificate revocation checks, because having a certificate expire on you for whatever reason is a sure-fire way to break the plant (and in some case possibly kill people), and overall a nuisance when trying to keep the plant running, while the threat it protects against can be handled elsewhere in the stack?

Security and safety are very often at odds - not just in emergency, but during regular operations.
