The idea of No Weapons allowed on school campuses has left the very people we want to protect vulnerable. I have had personal experience with this. The duck and cower approach to school shootings is a complete failure. Our children are ducking and cowering behind tables with absolutely no defense for them while the shooters (most all have had proven mental disorders) are randomly shooting and hoping to hit as many as possible. We MUST defend our children and teachers and staff from this violence. When our school was on lock down three times for shootings we had police show up promptly but what happens if they don't show up promptly? We need trained people who can help in this situation. While I don't wish it on anyone the facts are that it can happen to anyone and having trained staff available can help ward off problems in cases like this.
