A new academic article contorts facts and statistics to claim that a consultant’s review of documentation regarding police stop-and-frisks of pedestrians caused murders in Chicago.
- the state budget impasse was starving not-for-profits serving communities in Chicago (which are already starved for resources),
- the City released the video tape showing the police murdering Laquan MacDonald and proving that official reports of his death were false,
- the Mayor publicly admitted the CPD has a code of silence,
- the Mayor fired Garry McCarthy as police superintendent,
- the Mayor announced a new Task Force would investigate the CPD, and
- the U.S. Department of Justice announced that it was opening an investigation into the CPD.
Cassell and Fowler’s analysis does nothing to test whether these major events, or other unidentified factors, caused the police to perform fewer stops or caused Chicagoans to commit more murders. Instead, their math begins and ends by focusing on the drop in pedestrian stops, and only tests for correlation, not causation.
