What factors do police officers point to in explaining offending and victimization? A limited amount of prior research has addressed this question, despite the possibility that such theories impact police practice. Moreover, the findings that do exist are based solely on municipal police; yet a different socio-environmental context could lead officers to adopt different explanations. In the present paper, we draw on qualitative data obtained in interviews with campus police officers to explore how they explain common crimes on campus. They theorized petty larceny, underage drinking, and drug possession to result from a variety of factors, including opportunity, social learning, supervision, culture, peer pressure, the psychopharmacological effect of alcohol on crime, and deterrence; as a collective, these ideas form officers' rational choice theories. After presenting our findings, we suggest how officers' explanations of crime may be shaped by working in particular contexts and also affect how they police; implications for future research and police practice are discussed.
