Arizona’s top law enforcement official wants to allow one staffer in each of the state’s schools to carry a gun, a proposal pitched as a “golden mean” between allowing all teachers to carry weapons and doing nothing.

Attorney General Tom Horne, a Republican elected in 2010 with the motto “Defending Arizona,” has proposed a voluntary program in which every school could nominate one person to receive free firearms training provided by local sheriffs and the attorney general’s office. The individual would be allowed to keep a weapon in a locked place somewhere on campus.
