A large empirical literature has revealed the effects of preventative and punitive measures on crime. This column examines the effects of police deployment strategies, comparing geographically concentrated protection with evenly dispersed protection across a city. The results suggests that when considering changes in the geographic distribution of police forces, we should take into account the effects on house prices and on reallocation of the population, as well as the overall effect on crime in the entire city.
