The timing of an investigation after an officer-involved shooting (OIS) is influenced by conflicting forces. The public demands expedited resolution, but police officers are provided several protections that can delay investigations of their actions. This study conducts a randomized experiment to determine the impact of question timing after an OIS on the accuracy of police officers’ memory recall. Officers were randomly assigned to one of two groups. The treatment group completed a questionnaire after participating in a live-action, active shooter training scenario and again 2 days later, whereas the control group only completed the questionnaire 2 days later. Our findings suggest the timing of interviews after training did not influence officers’ recall of the scenario. There is little empirical understanding of how police officers reconstruct OIS events; further interdisciplinary research can help clarify these cognitive processes. This research could strengthen a traditional pathway to provide accountability for officers through investigations.
This study observes the spatial distribution of robbery using a multi-level framework to further understand the unique contribution of both micro-places and neighborhoods to the spatial variability of crime patterns. Mixed-effects regression models were estimated to determine if the influence of spatial interdependence measured with a spatial lag variable at street segments had a random effect between Chicago’s community areas. The variance parameters guided an exploratory spatial data analysis which revealed clusters of robbery patterns which were larger than crime hot spots and often nested within neighborhoods. We found there is an important distinction between places in Chicago where the spatial transmissibility of robberies is most acutely experienced across entire neighborhoods or within the immediate proximity of certain micro-places.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
