This study evaluates the impact of the LOV3 policy—which allows the police to mandate security guards topatrol and maintain order in public environments—on local crime rates in three locations within Malmö andHelsingborg, the two largest cities in southern Sweden, using data from March 2020 to November 2022. We useinterrupted time series analyses on daily crime data to assess the policy’s effects on reported crime rates. Ourfindings, 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
