Does Stop and Search Reduce Crime? Evidence from Street-Level Data and a Surge in Operations Following a High-Profile Crime

This paper uses a surge in stop and search operations following a high-profile murder to look at their effect on recorded crime. Difference-in-difference estimates using detailed geocoded data at the street-level suggest a doubling to trebling of the number of searches in streets close to the place of the murder. IV estimates on the effects of stops and searches on crime suggest little effect on property crime, weapons offences and violent crime or drug offences. Some specifications find reductions in anti-social behaviour, suggesting that any effects on crime are due to an increased police presence on the streets.
