The genesis of HunchLab was the idea to mine law enforcement agencies' CAD and RMS databases to detect unusual levels of activity in particular areas and then send alerts to the appropriate police staff. While crime analysis tools often are aiming to display what has happened, the concept of a geographic early warning system, such as within HunchLab, tries to answer the question: "what is unusual that is happening?" http://www.azavea.com/products/hunchlab/features/early-warning/
