New research by University of Utah S.J. Quinney College of Law Professor Paul Cassell has attracted national media attention in recent days.
Cassell will present his new research on April 4 at the University of Illinois College of Law . In the study, Cassell and University of Utah economics professor Richard Fowles used an econometric analysis to conclude that the 2016 spike in homicides in Chicago was caused by a reduction in the practice of stop-and-frisks by law enforcement in the wake of a settlement agreement obtained by the American Civil Liberties Union (ACLU) designed to limit stop-and-frisks.
Cassell and Fowles’ study, “What Caused the 2016 Chicago Homicide Spike? An Empirical Examination of the “ACLU Effect” and the Role of Stop-and-Frisks in Preventing Gun Violence,” concludes that fewer people would have died in Chicago if law enforcement were allowed to continue stop-and-frisk practices in policing.
The study was covered by the Chicago Tribune, Mother Jones magazine , KSL and Fox News.
Cassell also blogged about his research for Reason.com.
