[Note: This is an excerpt from "The Classroom Avenger," James P. McGee and Caren R. DeBernardo, Forensic Examiner (May-June, 1999). The study includes this important set of qualifications: "As a descriptive composite,[the "Classroom Avenger"] is not based on any type of statistical or actuarial model of prediction. Instead, it is both subjective and impressionistic and it is partially informed by a limited number of cases and an equally limited amount of fragmentary data and unconfirmed anecdotal accounts derived from official police reports and the popular media."]
