UMass Amherst Researcher Finds Police Killings can Discourage Engagement with Local Government

"The local community may go quiet after a police killing-and that's not a good thing," Shoub says. "Law enforcement actions extend beyond direct interactions with police and reverberate throughout communities. Officials need to collaborate between their agencies to overcome the tendency of citizens to disengage following a traumatic event."

Using the Los Angeles Times database of police killings and data published by the city from 2016 through 2020, Shoub and Drolc found that 311 requests for city services declined by an average of 14% during the same week of a police killing within one mile of the scene. However, they found no meaningful change in the number of 911 calls using the same criteria.

"We think this indicates that the relationship between the public and the police is already so bad in certain areas of L.A. that people are already contacting police at the lowest rates possible-only when they have no other choice, which we believe is why 911 calls didn't decline following a police killing," Shoub explains.

For a broader view, Shoub and Drolc designed and fielded a national survey experiment of 2,037 U.S. adults who were asked to read one of three randomly assigned hypothetical news reports about a police killing, a police food drive or a control story about an animal shelter encouraging residents not to adopt a rabbit for Easter. The experiment found that respondents who were assigned the article about the police killing were less likely to say they would contact the police for help, viewing the local government as less representative and trustworthy.

The study follows research published by Shoub in 2023 showing a higher rate of voting following police killings.

"Voting can be seen as taking hold of and exercising your voice," Shoub says. "Whereas this study of engagement is based on the premise that government is there to help and, at the bare minimum, won't hurt you."
