Using algorithms to forecast where and when crimes are likely to occur, based on historical data.

When to use it
Use predictive policing when traditional methods of crime prevention and resource allocation are insufficient. Predictive policing algorithms synthesize historical crime data to forecast potential crime hotspots, enabling targeted patrols and resource deployment to areas like high-theft neighborhoods.
Quick example
In New Orleans, the police department uses predictive policing software to allocate patrols more effectively. The system analyzes past crime data to identify potential future crime locations and times. This tool is an instance of predictive policing, as it directly uses historical data to guide policing strategies.
Ecosystem
Predictive policing sits within a broader ecosystem of public safety and law enforcement technologies. It interacts with data collection systems and crime analysis tools.

Misconceptions
| Misconception | Rebuttal |
|---|---|
| It predicts individual criminals | It forecasts crime locations, not individuals |
| It's 100% accurate | It's probabilistic, not definitive |
Trade-offs
- Resource efficiency — potential for biased data influencing outcomes
- Proactive policing — increased surveillance may raise privacy concerns
