This study evaluates the impact of the LOV3 policy—which allows the police to mandate security guards to patrol and maintain order in public environments—on local crime rates in three locations within Malmö and Helsingborg, the two largest cities in southern Sweden, using data from March 2020 to November 2022. We use interrupted time series analyses on daily crime data to assess the policy’s effects on reported crime rates. Our findings, which reveal no significant impact of the LOV3 policy on reported crimes in the examined locations, underscore the need for further research and refinement of crime prevention strategies.
