In order to address the people who are affected by violence in schools, numerous things can and should be done. Aside from that, teachers have gotten together and formed groups to help them deal with adolescents and youth violence. The changes that need to be made can range from just simply talking to students about the dilemma to tightening down on security.
Some schools now have surveilance cameras and metal detectors.
Another way is to severly punish those who are causing the trouble. A way to campaign and promote awareness could be done in so many ways. As mentioned before, programs and organizations can be formed and not only by teachers, but by students as well. The students who actually want to learn and are tired of being disrupted can get together and form a group that adresses the problem and then comes up with multiple solutions. These groups can bring in students in their area by advertising with bumper stickers and posting info on billboards.
