It's a technique shown to work. Consider that in Tacoma, WA, where the tool is used in the city's Burglary Reduction Initiative. The Tacoma Police Department reduced residential burglaries by 22%, and commercial burglaries by 8%, in the first year of its use.
"We exceeded the two-year goal in the first year by a wide margin," Assistant Chief Peter Cribbin reported to The News Tribune.
PredPol uses data from an agency's RMS to track the what, where, and kind of event, which can provide insight into where crimes are likely to occur next. "We only use crime type, crime location, and crime data and time; the most purely objective information available. We don't use demographic information, economic, racial, or any personally identifiable information," says Brian MacDonald, CEO of PredPol.
Agencies select the crimes to target, MacDonald adds, noting the system works well for street crimes, burglaries, auto theft, robbery, and assault.
The solution is designed for use by patrol officers who log in to the system to obtain a map with a series of red boxes overlaid on it. The red boxes signify where crime is most likely to occur during their shifts. If they click on a box, they might find that area had 17 auto thefts in the last six months, four robberies and two car break-ins. Officers are then encouraged to spend some time in the identified areas during their shift.
