Another way to look at it (and it works all over the planet
)
Question: is it an EMERGENCY?
NO: as in this case, as the "only" person in danger is a pax. Then you better abide to all rules
YES: say if the "old man" dies or some other interesting snag, then you are in a case of emergency and allowed to bust 'em all
So, as a matter of fact, just see if it qualifies as an emergency or not, and then make your decision!
