Just the principal at your daughter's school, or every principal of every school, in the entire nation?

If so, I bet you would have many, many more deaths under such a scenario than you would ever have if they all remained unarmed. I could give you plenty of examples, but I would start with irate students locating such a gun that was accidentally left out (or not), principals 'going crazy' (either emotionally over an ex-spouse,etc. or literally a mental disorder), etc., etc.
