Of course, this would be for teachers who choose the option and are trained in the use and handling of a firearm. Best scenario, lunatic doesn't even enter school because he knows some of the staff are armed.
are you serious? more like a teacher goes postal cuz their wife left them (or husband), they are sick of their crappy pay and obnoxious kids ... and the principal just pissed them off one too many times ... they are more likely to use the guns on staff and kids than intruders ... LOL ...
