If people wanted to really hurt people badly at school and didn't have a firearm, they could easily do it... For example, what if they made an explosive device from house hold chemicals? Or made Chlorine Gas from house hold chemicals... See my point? If kids are going to kill other kids, they will do it whether they have a gun or not... And another thing, we all know have libral and biased the US News Media is, so what are the chances that non-firearm related incindents have occured at public schools, but were not reported?
