This paper devises a system of differential equations to model the dual dependency of police and crime, based on a predator/prey relationship. It emphasizes the complexity of the relationship and shows how empirical research can be skewed if it only focuses on a limited time interval. The system of differential equations explains why some researchers have come to the mistaken conclusion that hiring more police induces more crime, and gives policy makers better information with which to make decisions.
