LAPD Pedestrian and Motor Vehicle Stop Data Analyses

Analysis Group was retained by the City of Los Angeles to analyze data on police stop and search activity for possible evidence of racial profiling by LAPD officers. Under a Consent Decree with the Department of Justice, data on pedestrian and motor vehicle stops, including the perceived race of those who are stopped, have been collected by LAPD since 2002. The Analysis Group case team led by Senior Advisor Bruce Strombom and Managing Principal Mark Gustafson recommended a number of analytic and statistical techniques for evaluating these data. These techniques were designed to determine whether, after controlling for legally valid influences on law enforcement activity, minorities are stopped and/or searched at a disproportionate rate compared to non-minorities. Analysis Group completed its study and presented a final report to the City of Los Angeles.
