Police officers do a significant amount of high-stake writing in police reports, but report writing is given little attention in policy academies, and prevailing guidelines treat the task as a mechanical process of recording facts. As a result, officers are ill-prepared for this essential and inherently complex task. In this study, we interviewed officers to study what makes for a good police report. Our findings reveal that police reports are goal-directed genre actions. This understanding peers through the positivist emphasis on factual details to emphasize the social function of police reports in the criminal justice system.
