Policing crime patterns is hard business. Atlanta, Georgia, is no different than any other jurisdiction in this regard. Every day sees new crimes added to the database; and every day, the Atlanta police seek to use these data to not only respond to victims, but also to try to get out ahead of emerging hotspots and prevent crime in the first place. Until recently, the Atlanta Police Department (APD) followed a system for daily mission planning that combined hotspot mapping with the selective use of street-level intelligence. Beginning in July of 2013 for 90 days, the APD added predictive policing to the mix in two policing zones, targeting burglary, car theft, and robbery. Aggregate crime declined by 8 percent and 9 percent in the two zones compared to the prior 90-day period, with burglary and car thefts falling 10 to 28 percent. Aggregate crimes in the zones that did not deploy predictive policing increased from 1 to 8 percent.
