The only other realistic alternative is to allow teachers and staff that have a concealed handgun license to carry handguns in school. If the school opts to do so, it could provide additional training to teachers and staff wishing to carry handguns in school, so long as the school provides this training at no expense to its personnel. It is quite likely that local police departments and sheriff departments will be more than happy to create training programs for such persons and provide the training at little or no cost to the school district.

This is really the only way I would be comfortable with any teachers or staff carrying in a school. There are a lot of factors to consider in a school active shooter situation that are not covered by the CHL course. I would be very happy if they provided a few days of active shooter and intermediate pistol training in order to allow faculty or staff to carry.
