Good point, the gun was owned by a teacher, the very person we gun owners want armed at school.Of course, you would think that pro-gun activists would choose not to stand behind this argument after a massacre in which guns owned by a teacher were used.
But in this case, I find it suspicious a female teacher owned an AR15, a Glock and a Sig. Did she purchase them for her son (and was this school shooting instigated by the gun-haters)? And what if a TEACHER decides to shoot kids at school ? Does it mean other ARMED Teachers can't protect kids from shooters/murderers ?
Gun Free School Zones are gun free slaughter zones, period. Banning guns means banning all of our weapons, leaving the biggest strongest males with an advantage over everyone else. Worst of all, it will leave the Govt armed, leaving us (we the people) disarmed and vulnerable to our worst enemy (the Govt).
