A recent article on stops and searches by the Metropolitan Police in London has reignited debate about the use of stop, question, and frisk (SQF) in the United States. Piquero and Sherman (2025)1 analyzed 15 years of stop and search data from the Metropolitan Police and found a correlation between increases and decreases in stop and search encounters (SSE) and subsequent rates of serious injuries and homicides in London, primarily from knife attacks. In short, knife-related assaults and deaths went down when British police stopped and searched more people in public, and they went up when police stopped and searched fewer people. What do these findings mean for U.S. law enforcement? Should police in America stop and frisk more people as a strategy to reduce violent street crime, crimes that in the U.S. usually involve guns rather than knives?
