Both of my parents were teachers. Both of them have had permits for concealed carry. Neither would ever bring a gun to school or think they should be the first in the line of defense, and they were gun owners.
That’s two gun toting teachers’ opinions.
However, let’s stick with basic statistics: fewer guns means fewer gun homicides.
That should be basic enough math for you.
Good luck with the three Rs [not Russia, Republicans, and R — um, ignorant].
