Predictive Policing

Predictive Policing

Predictive policing refers to the use of analytical techniques by law enforcement to make statistical predictions about potential criminal activity.2 Predictive policing can involve either predicting events (i.e., forecasting when and where crimes are likely to occur) or people (i.e., individuals likely to be victims or perpetrators of crimes). Instead of relying on an officer’s ‘hunch’ about a...

Runaway Feedback Loops in Predictive Policing

Predictive policing systems are increasingly used to determine how to allocate police across a city in order to best prevent crime. Observed crime data (arrest counts) are used to update the model, and the process is repeated. Such systems have been shown susceptible to runaway feedback loops, where police are repeatedly sent back to the same neighborhoods regardless of the true crime rate. In ...

Randomized Controlled Field Trials of Predictive Policing

The concentration of police resources in stable crime hotspots has proven effective in reducing crime, but the extent to which police can disrupt dynamically changing crime hotspots is unknown. Police must be able to anticipate the future location of dynamic hotspots to disrupt them. Here we report results of two randomized controlled trials of near real-time epidemic-type aftershock sequence (...

Predicting Financial Crime: Augmenting the Predictive Policing Arsenal

Financial crime is a rampant but hidden threat. In spite of this, predictive policing systems disproportionately target “street crime” rather than white collar crime. This paper presents the White Collar Crime Early Warning System (WCCEWS), a white collar crime predictive model that uses random forest classifiers to identify high risk zones for incidents of financial crime.
