An unanticipated finding was the absence of strong empirical support for school gang violence. The evidence does show youth gangs have changed dramatically over the last several decades and have become more violent, largely due to drugs and weapons-carrying. One major impact of this violence on schools has been the dissolving of the school as the "neutral zone," where gang activity ceased. Thus, it appears that the "turf" issues of the street gangs have infiltrated the schools. The review explores problems related to school gang violence definitions and literature, trends in school-related gang activity, reasons for gang membership, at-risk youth, and proposed strategies for ameliorating the problem. The article does not attempt to explore the history and theory of youth gang development in the United States, except where such a discussion relates to the school setting. References
