In EP11, I interview Professor Lawrence W. Sherman, the Director Jerry Lee Centre of Experimental Criminology at the Cambridge Institute of Criminology (IoC), the Chair of the Cambridge Police Executive Programme, and the former Director of the IoC. We cover: Sherman's path to criminology; experimental criminology (e.g., randomised control trials) and causal inference; addressing gun violence in the US; police shootings; the futility of police research in the US; Cambridge Journal of Evidence-Based Policing; "why black people commit more [violent] crime?"; the ideal police recruit; police culture and the organisation; Sherman's biggest regret (not reducing police killings); "what are you most proud of?"; Sherman's worldview (bounded utilitarianism); rapid policing response by video; machine learning and "minority report"; final words for police recruits and criminologists.Professor Lawrence W.
