Samenvatting

Law enforcement around the world, including the Netherlands, is currently experimenting with predictive policing: policing based on crime predictions. Big Data on past crimes and the help of sophisticated machine learning enable police to use reliable predictions about when and where the next offense will take place. If the effectiveness of policing actions is stored in the system, it can also predict which intervention is most effective. This is called prescriptive policing. The authors explain how these methods work, how reliable and effective they are and which associated risks can be identified. The authors emphasize that legal, ethical and organizational safeguards are necessary for a responsible implementation.
