If they already have a CCP and their own weapon to carry. I don't want to force teachers who don't want to carry guns to do so, nor should guns be handed out like candy. There should also be a trained officer or 2, but having some teachers with guns isn't a horrible idea. This way schools are safer, and chances of accidental shootings only marginally increase because only those teachers competent to carry a gun are allowed to do so.

Honestly they should just install automated turrets in the roof. I know I wouldnt have done half the crap I did with turrets watching my every move.
