How could arming teachers be regulated?  If teachers can bear arms, then what’s to stop other people in the school environment in contact with children, such as janitors, from demanding they should too, or even getting hold of them illicitly? Many of them won’t have been certified or checked, and as such there is no guarantee that the system of only allowing teaching staff to carry them could be fully regulated. This is particularly the case if janitors, cafeteria workers or cleaning staff have private gun licences of their own. The result is that children could be in an environment where those not licensed to carry arms around them would have greater opportunities to do so, thereby increasing the threat to children. It would be difficult to monitor which staff are bringing guns into school without a lot of investment in searches and detectors – money that could have paid for professional security. It is thus arguable that the proposition’s mechanism does not stand.
