FWIW, your rationalize that its okay to yell FIRE in a crowded theater as long as no one gets hurt and as long as their are no injuries.
If you do not have a responsibility to be aware, it is not possible for you to have a duty. How can you be held responsible for something you cannot be expected to know?
If people are to be required to have a duty to intervene in police responses happening halfway across the country, they must have a responsibility to make a reasonable effort to monitor them.
As far as fire alarms are concerned, that is a horse of a different color. A fire alarm is a report to the fire department, and a request for help. That is, quite properly, subject to penalty if done falsely. That did not happen here, at least during the period all the money was being spent.
As far as yelling "fire" in a crowded theater is concerned, nobody yelled anything here. There was no hazard created, so that does not really apply, either.
