Stop school shootings by allowing metal detectors

I believe that our kids have a right to a safe place to learn and make friends. We need better security that what is out there. There should be some sort of metal detection or similar security to stop the violence. Today (12/14/2012) 18 students and 8 staff members were shot inside Sandy Hook Elementary. Before that, we had many others such as Columbine. This needs to end. METAL DETECTORS FOR PUBLIC SCHOOLS. THANK YOU
