Exactly. Regulations and rules that will be enforced by the company must be in the operational library, IE. OMA, FCI, FCN etc etc. You are not required to read ASR summaries, weekly update, fleet facts, corporate communication etc. But you are required to know the books so again, once its in the OMA then I'll comply. Why do you think they put it in a weekly update? Why does this not apply to security in departures? Why does this not apply to security for passengers?
This is only because some oxygen thief is trying to save their job or someone in HQ security doesn't know the rules of theirs.
