This study examined the consolidation in police services in a historically high-crime, disadvantaged urban setting (Compton, California), which began contracting with the Los Angeles County Sheriff's Department (LACSD) after the closure of Compton Police Department in 2000.
Abstract
The utility of police consolidation, particularly police contracting of services, has received widespread attention in academic and practitioner circles; however, the bulk of empirical research centers on potential fiduciary benefits; only limited scholarship has explored the possibility that changes in police services may correspond with differences in crimes solved and offenses observed. The current study used independent samples difference in means tests to examine variations in crime clearance rates prior to and following the transition in Compton. Group-based trajectory analysis combined with difference-in-difference regression estimation was used to assess changes in criminal offenses, while minimizing selection differences in comparison settings. With the exception of homicide, clearance rates for six Part I crimes experienced statistically significant improvements in Compton's post-contractual period. In addition, although the vast majority of Part I offenses remained stable during the transition to LACSD policing, burglary crime rates experienced a statistically significant and sustained decline, net of controls. The study concludes that a primary concern with police contracting centers on a lack of local police control, disconnect between local needs and actual services provided, and the potential for backlash related to a reduction in the quality of police services. The findings of the Compton suggest that contracting with a well-resourced agency experienced in police consolidation has the ability to maintain and, in some circumstances, improve the quality of law enforcement services.
