Arizona wants to Arm School Principals

I was just watching a DVR of CNN yesterday. The Arizona Attorney General wants to arm public school principals of all public schools in Arizona. So we now have 3 states either arming teachers, principles or training them to use pistols to protect children. The three states now are Texas (where in Harrold, Texas teachers in that public school have been armed with concealed weapons for 5 years), Utah which is starting to train 200 teachers to carry concealed weapons, and now Arizona which is starting a bill through the legislature to arm principals and possibly other teachers in their public schools as well.
