Predictive Policing in Phoenix

Algorithmic crime-fighting, based on predictive technology makes makes me nervous.  Let me just say that upfront.

Predictive Policing

There is not a whole lot of academic information on predictive policing, in part because predictive analytics is such a young field in and of itself.

Probably the best definition I could find of this mysterious topic came from the RAND Corporation, a non-profit global policy think tank.

Predictive policing is the application of analytical techniques—particularly quantitative techniques—to identify likely targets for police intervention and prevent crime or solve past crimes by making statistical predictions.

Through an analysis of existing academic papers, vendor literature, and police use of predictive analytics the RAND Corporation came up with four types of predictive policing.

  • Predicting crimes – forecasts places and times with an increased risk of crime
  • Predicting offenders – potential for an individual to re-offend in the future
  • Predicting perpetrators identities – profiling likely offenders
  • Predicting victims of crimes – identify groups or, in some cases, individuals who are likely to become victims of crime.
