Gang Hot Spots Policing in Chicago: An Evaluation of the Deployment Operations Center Process.

摘要

From 2000 to 2007, Chicago experienced a significant decline in violent crime (murder, criminal sexual assault, robbery, and aggravated assault/battery), particularly gun-related public violence. In public discourse, this decline was attributed to the Chicago Police Department (CPO) and, in particular, to a process spearheaded by the Deployment Operations Center (DOC). The primary mission of the DOC was to analyze crime and intelligence data, identifying areas of the city believed to have a high probability for violent crime (i.e., violent crime 'hot spots'). Areas identified by DOC analysts, termed Level II deployment areas, were used to guide deployment decisions for specialized units, whose responsibility was to enter designated hot spots and suppress gang, drug, and gun crime.The primary purpose of this study, funded by the National Institute of Justice, was to evaluate whether the aforementioned crime reductions could be attributed to the DOC process. To accomplish this, researchers used both qualitative and quantitative research methods, collecting data on various elements of the DOC logic model - analysis of crime and intelligence data, identification of hot spots, communication of designated hot spots to CPO personnel, redeployment of officers to hot spots, and engagement in suppression activities. CPO administrators believed that.
