The discussion notes that analysis for crime prevention differs from analysis of crime prevention in that it informs efforts to identify and address specific crime threats at specific times and places. Analysis for crime prevention identifies concentrations of either crime as a whole or single offenses where prevention efforts may be effective; helps find the most efficient, effective, and, perhaps equitable means of prevention; and can help forecast likely future crime problems to aid the development of preemptive strategies. A substantial array of research findings exist that can inform the targeting of prevention efforts in terms of victims, products, places, and offenders. Particular efforts to reduce or prevent crime require the identification and definition of local problems and the determination of what might be done to address them. Determining the replicability of past initiatives is complicated. Findings of effectiveness in one context cannot mechanically be transposed to another situation with expectations that precisely the same results will occur. The role of the expert crime analyst is to sharpen definitions of problems based on understanding of well-developed and tested theory. The eight subsequent papers in the same volume focus on these topics and include empirical research studies and findings from work with specific programs and strategies. 37 references
