As written, your statement above would indicate you think it UNLIKELY that a school bus parked at the Adventure Science Center would NOT be considered "property owned, operated, or used by a school or educational institution". In other words, you would think it likely that it was property within that description. I suspect, however, that the double negative is not really what you intended here, given your use of the phrase "just because". If what you meant is that it is unlikely that the bus would be considered to be on "property owned, operated, or used by a school or educational institution" then I agree with you. It is not property owned, operated or used by a school, and I don't think the Adventure Science Center would fall within the definition of an "educational institution". In any event, it's pretty clear that an apartment complex parking lot is not included with the reach of the statute.
