Prospective
crime mapping in operational context - Overview of full report
Predicting crime is the stuff of science fantasy. However, there are patterns
which make useful prediction possible as a routine part of policing. Domestic
burglary, for example, clusters in space and time. When a burglary is experienced,
another is likely nearby and soon. The elevation in burglary risk declines over
time. The subsequent burglary is likely to occur around the same time of day.
In the research reported, a burglary forecasting tool (ProMap - prospective
mapping) was developed, yielding risk predictions for clusters of homes which
were significantly more accurate than alternative approaches to mapping risk.
ProMap was rolled out in one police Basic Command Unit (BCU) for a trial six
month period, and a process evaluation conducted. After teething troubles, it
became clear that there were no major practical obstacles to ProMap implementation.
Most police officers came to see Promap as useful, enquiring if it could be
adapted to predict other crimes.
Extending ProMap to other crime types and places, we envision a sophisticated
way of optimizing police patrols in real time, thereby offering advantages to
police and local authorities in crime reduction and detection.
