So how much do you think insurance will cost the school district if teachers are armed? One mishap lawsuit could close down the district. Arming teachers is a bad idea all around. I think a lot of people who suggest so are thinking some perfect scenario and not reality scenarios where people die in cross fires or are blown away by law enforcement.

Even bullet proof windows and heavy security doors which are locked down during school hours are not 100% but a lot safer than relying on teachers to get it right under fire.
