An Arizona Senate panel voted to allow staff and students at Arizona Colleges and Universities, which will include Tucson, to carry arms for their protection. They did not pass this bill for K-12 schools. It does appear that there are enough votes to also permit guns in K-12 schools. This legislation only allows someone to carry a weapon on campus who has a permit, and in order to obtain consent to do so, they have to pass certain conditions as well as be at least 21 years of age.
