That's very interesting, so he can't claim ignorance since as Principal, he was responsible for making sure every teacher (and student) knew where the fire alarms, extinguishers, and hoses were, along with the location of the emergency exit doors, and which doors they were required to take their students through, and where to assemble them outside the school. Not only that, but I'm guessing he was also required to make sure there was an evacuation plan posted in every classroom, along with the mandatory wall signs, and overhead signs posted to give direction where the emergency exists were. I'm sure all of that was part of the school district's regulations required of him as a Principle in regards to fire safety, and other emergencies that could occur within the school.
