This discussion of armed people in schools is odd given that my children, youngest 33, experienced an armed protector in their high schools. That was 15 years ago. My boys still know the guy's name and speak of him with affection; he was well liked by all. I just assumed that having an armed, trained protector at schools was the norm; guess not, at least in the blue states. It is difficult not to believe that having a guy in school like my children had, deters gun violence and actually all violence.
