I think, that if teachers were allowed to carry a pepper spray device, they could possibly stop an armed kid from killing other classmates, or at least slow him down, blind him and be able to safely grab him and stop the killing. If teachers carried a pepper spray device with a loud air horn it would alert everyone that there is a situation while disabling armed kids, less people would be killed. What if teachers and school personnel carried a pepper spray device with a loud air horn and a video camera that would video record the event. I think it would be a good thing. The Defend Alert ID would be Ideal for this kind of situation. That is one of many reasons I developed it. What is your opinion ?
