The available scientific evidence on the crime reduction value of focused deterrence strategies has been previously characterized as “promising” but “descriptive rather than evaluative” (Skogan and Frydl, 2004: 241) and as “limited” but “still evolving” (Wellford et al., 2005: 10) by the U.S. National Research Council’s Committee to Review Research on Police Policy and Practices and Committee to Improve Research Information and Data on Firearms, respectively. Our systematic review identified ten evaluations of focused deterrence strategies; nine of these evaluations were completed after the National Research Council reports were published. A betterdeveloped base of scientific evidence now exists to assess whether crime prevention impacts are associated with this approach.
