Negative interactions between the public and government agencies, particularly with law enforcement, have long been thought to reduce political participation and trust in government. However, less attention has been given to how negative events in government-citizen interactions shape civic participation and broader policy feedback. Specifically, little research has examined how government contact, whether personal (e.g., being arrested) or proximal (e.g., a family member is arrested), informs public engagement with local services. To fill this gap, we focus on police killings and their impact on the public’s willingness to engage with local public services.
Theoretically, we draw on the policy feedback literature, which explores how personal experiences with government and government agents influence political participation and public evaluation of government. This framework suggests that government decisions send community-wide signals about the public’s value in the eye of the state, which in turn leads to disempowerment and reduced willingness to engage. Additionally, negative government actions–even when indirectly experienced–undermine perceptions of government legitimacy and thereby reduce participation. Based on these insights, we hypothesize two potential outcomes: the “Police Particular Hypothesis,” where a local police killing reduces engagement with the police specifically, and the “Diffuse Government Hypothesis,” which posits that such negative events decrease participation with local government services more broadly.
To test these hypotheses, we conducted a two-part study. First, we used observational data from Los Angeles, including 911 emergency calls and 311 non-emergency service requests from 2016 to 2020. We use a generalized difference-in-difference approach with matching to explore the effect of police killings on these two types of public engagement. Second, we conducted a survey experiment where participants were exposed to one of three randomly assigned news clippings, including one about a local police killing, and compared their willingness to engage with local government.
The findings demonstrate strong support for the Diffuse Government Hypothesis. In the weeks following a police killing, the number of 311 service requests dropped significantly, indicating that negative interactions with the police led to broader disengagement from local government services. However, there was no significant change in 911 emergency calls, suggesting that despite the negative events, the public still sees the police as essential for emergency situations. The figure below illustrates such relationships over time. The survey experiment further confirmed these findings, showing that participants exposed to the police killing vignette were less likely to trust and engage with local government. However, it also showed a reduction in the likelihood that someone would reach out to the police, providing some support for the Police Particular Hypothesis and suggesting that we might have observed floor effects in the observational study.
This study contributes to our understanding of how negative events in government-citizen interactions affect community participation, expanding on policy feedback theories that traditionally focus on political participation. The findings have important implications for policymakers and public managers, highlighting the potential for spillover effects from negative events, such as police killings, to erode broader government legitimacy and engagement.
