- Copper, C.S. (2014). Assessing the practice of hot-spots policing: Survey results from a national convenience sample of local police agencies. Journal of Contemporary Criminal Justice, 30, 123-146.
- Abstract: This study examined the practice of hot spots policing as reported by a convenience sample of predominantly large municipal police agencies. Police commonly defined hot spots in terms of micro places as well as larger areas, and they emphasized short-term identification and responses to hot spots. Respondents identified problem analysis/solving, targeting offenders, and directed patrol as the most common and effective strategies for hot spots, but there was wide variation in their views of the most effective strategies for different types of hot spots. Current practices could arguably be improved through more a precise geographic focus, a greater emphasis on chronic hot spots and their criminogenic features, and further research to determine optimal strategies, dosages, and proactive uses of hot spots policing.

- Braga, A.A., Apel, B. & Welsh, B.C. (2013). The spillover effects of focused deterrence on gang violence. Evaluation Review, 37, 314-342.
- Abstract: Background: Focused deterrence strategies attempt to increase punishment risks faced by violent gangs through the development of new and creative ways of deploying traditional and non-traditional law enforcement tools. In addition to increasing the swiftness and certainty of sanctions, these strategies explicitly communicate incentives and disincentives to deter likely gang offenders from violent behavior. Objective: This study seeks to determine whether focused deterrence strategies generate spillover deterrent effects on the gun violence behaviors of vicariously treated gangs that were socially tied to directly treated violent gangs. Research Design: A nonrandomized quasi-experimental design was used to evaluate the gun violence reduction effects of focused deterrence strategies on directly treated gangs and vicariously treated gangs. Propensity score matching techniques were used to identify balanced comparison gangs for the vicariously treated gangs. Growth curve regression models were used to analyze gun violence trends for treated gangs relative to comparison gangs. Unit of Analysis: Quarterly counts of fatal and non-fatal shootings involving specific street gangs between 2006 and 2010 served as the units of analysis. Measures: Key outcome measures included quarterly shootings committed by specific gangs, shooting victimizations suffered by specific gangs, and the total number of shootings involving specific gangs. Results: The focused deterrence strategy was associated with statistically significant reductions in total shootings by directly treated gangs and vicariously treated gangs. Conclusions: Our study finds that vicariously treated gangs were deterred by the treatment experiences of their rivals and allies. This suggests that focused deterrence strategies can generate spillover crime reduction effects to gangs that are socially connected to directly treated gangs.
