No, we most certainly should not arm teachers. No, no, no! That's not a solution, only a recipe for more problems -- and a lot more dead students. Besides, now we know that a trained sheriff's deputy who was on-site at the school did nothing. What makes us think that untrained teachers would, under pressure, perform any better? They might fail to shoot the assailant, and maybe just shoot an innocent student. We should talk this out -- and also discuss how gun nuts who want to be prepared to overthrow a tyrannical government are sinning against the original intent of the 2nd Amendment.
