A. The main Idea of this article is violence on college campuses.
B. The topic is there are many ways security on campus can prevent violence.
C. The author uses many supporting details to support the main idea such as stating college campuses should use more security cameras, a higher level of security, and also says that classrooms should have locked doors so no body can randomly enter a classroom. Also by educating students about violence can help stop a problem before it even occurs.
3. Three characteristics that can be early warning signs of a student's potential to become violent are someone who's socially isolated, has low self-worth, doesn't take criticism well.
4.I feel that the security system in our school is good because I always notice a security car driving around campus during all hours of the day, they do a good job and are always looking for anybody who looks suspicious or for somebody who does not belong there.
