I live in the district where the Columbine masacure took place. ever since that happened, you never hear very much about any school shootings. where did this school shooting you are talking about take place? I don't feel the safety of our children has changed that much. though there are very strict rules about anything that can be construed as a weapon. That can include, but is not limited to the misuse of a pencil, sissors, or even a paperclip. If a student brings to school a nail clipper or a metal nail file they can be expelled. The basics of it is that if it can be construed as a weapon the child can face expulsion. Every incident is suppose to be reported to the police. the police look into every case and record it.
but really what we have to look at is why are the kids doing this? For the thrill? For the hate they have in themselve? But what causes the need to do it? Until we look at the deeper reasons, there will be more shootings. and more deaths and suicides.
