New study by Cassell on cause of Chicago homicide spike attracts national attention

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.
