The study concluded that crime prevention strategies would require the intervention of both the police and city planners to be reasonable successful. It also noted that the establishment of accessible police stations would complement the effects of the police in their endeavor to combat crime in Manzini.

Author: Weber, Lloyd E. Title: The Illicit Methamphetamine Landscape of Franklin County, Missouri: Application and Analysis of a GIS-based Risk Assessment Model Summary: Illicit methamphetamine, a synthetic, highly addictive drug, has gained national attention because of its destructive properties. Between 2002 and 2004 close to 400 clandestine methamphetamine labs were seized in Franklin County, Missouri. This study reviews documented methamphetamine production risk factors and examines a spatial model based on the reviewed risk factors. The risk factors include populations that are rural, white, impoverished, undereducated, unmarried and aged 25 - 29. The model is advanced by adding a component representing a clandestine landscape. Model output is validated using illicit meth lab seizure data supplied by Franklin County law enforcement. The model components are tested using both ordinary least squares and geographically weighted regression. This study found that the model is successful in indicating areas that have the potential to develop methamphetamine production problems. The model also was successful in indicating areas that would not likely develop a meth production problem. Ordinary least squares regression analysis indicates that every model component, with the exception of percent white and percent unmarried, are positively correlated with meth production in this case study. The results from the geographically weighted regression analysis show percent rural, percent poverty and percent clandestine landscape vary significantly across the county and indicate which areas these components have the most effect in developing and sustaining an illicit meth landscape.

Author: Caplan, Joel M. Title: Risk Terrain RTM Modeling Manual: Theoretical Framework and Technical Steps of Spatial Risk Assessment for Crime Analysis Summary: Risk Terrain Modeling (RTM) is an approach to risk assessment that standardizes risk factors to common geographic units over a continuous surface. Separate map layers representing the presence, absence, or intensity of each risk factor at every place throughout a terrain is created in a Geographic Information System (GIS), and then all risk map layers are combined to produce a composite “risk terrain” map with attribute values that account for all risk factors at every location throughout the geography. RTM aids in strategic decision-making and tactical action by showing where conditions are ripe for events to occur in the future. This manual is offered as a primer on risk in the criminal event and demonstrates effective ways to apply RTM to crime analysis and policing operations. It begins with a review of the RTM approach to spatial risk assessment and presents a short overview of the theoretical underpinnings of criminological theory that have addressed the social and environmental factors that contribute to crime patterns, hotspots, and risk terrains. The second part details the technical steps for analysts to take in using ArcGIS software to develop risk terrain maps. The third and final part presents ideas of how RTM works in strategic and tactical decision-making, particularly within the context of the ACTION model for risk-based intelligence-led policing. With this manual, analysts can produce risk terrain maps that give actionable meaning to the relationships that exist between place-based indicators and crime outcomes. Planners can use this approach to develop strategic models to forecast where crime problems are likely to emerge and to engage in steps that might reduce risks of crime occurring in the future.
