The thing is, BZ, when you're talking about private schools, they have been deemed tax exempt due to their benefit to the 'common good.' Fire departments are government services which are all tax exempt (for partly the same reason). Public schools, similarly, are also government services.
The US government has established that emergency services have the liability (financial or otherwise) to absorb such burdens due to (among other reasons) the obvious benefit of being tax exempt in the first place, even though this is not the primary function.
I'm not aware of any exception which would allow for a legal implementation of such fees, fines or offsets. Are you?
Perhaps this will help bring you up to speed:
Everyone's entitled to their own opinions, but not their own facts.
