More than half of U.S. schools have no police presence on their campuses. Jonathan E. Collins proposes that all school buildings be free of police. School resource officers (SROs), he writes, do more harm than good. An alternate policy that would remove SROs from schools involves the framework of the community policing model. This model focuses on engaging students in full and deep discussions and problem-solving that reveals what students think of school safety and the root cause of school violence.
