They are doing it in Texas; if they can do it in Texas they can do it everywhere.
I would rather my children go to a school where they have armed guards to protect them; than go to a school where some damn fools put up a sign claiming "GUN FREE ZONE".
Until you place a sign in front of your home saying
"THERE ARE NO GUNS IN THIS HOUSE, WE ARE DEFENSELESS"
neither you nor anyone else has the right to prevent armed guards from protecting our children while they are in school!
