Presentation: The biggest hotspot RCT ever, Operation Avert
This paper presents the surprising results from London’s Operation Avert, which is in all likelihood the single largest experimental trial of hot spot policing ever conducted. 228 high violence locations were randomly assigned to a number of different daily patrol conditions using crossover random assignment. With tens of thousands of location-days in the analysis, this study presents some challenging findings, especially in policing complex global cities.
