In the past few years, the developments in crime analysis, especially geographic analysis, have been stunning. Just 10 years ago, the job of making a map and table depicting residential burglaries in a given locality over the course of a month was a task that easily would have consumed a crime analyst’s entire morning. Moreover, doing so required a fair knowledge of structured query language, one of the best PCs money could buy, and a few thousand dollars’ worth of software. Learning to use the software was daunting, and the proficiency curve was steep. All of these factors dramatically limited the availability and utility of these tools. Today, this same task can be completed by staff with little or no training in a matter of minutes by clicking a few times on an Internet crime mapping application.
