Whenever a student pulls the fire alarm, the fire department presses charges if it's a false alarm. It isn't much of a deterrent, because most of these types of things are anger-impulse when kids "don't care" anyway, but as after the fact consequences of their actions come home on them, they start realizing that there are other people in the world who are affected by their actions, too.

I made certain to let my boss know I that I do check with clinicians about material I think might be problematic, and named the names of the clinicians, too, so she can check on that by name if she feels the need to do so.

(On the defensive much, me? Just a lot.) Thank you for the good advice. It marches well with my feelings, too.
