A seminal piece in our understanding of how high-profle cases of police violence can affect communities, Desmond, Papachristos, and Kirk (2016), found that resident calls to the police via 911 significantly declined after the beating of Frank Jude. These effects were especially prevalent in primarily Black neighborhoods. In this study, we used an interrupted time series design to replicate the original results in a different city using a fatal incident of police violence. We also extended the methods of original study by further disaggregating the follow-up effects to include officer-initiated events, which capture more discretionary activity for patrol officers. Our results confirm the original findings, with resident calls to 911 declining in majority-Black neighborhoods after a deadly incident of police violence, signifying a decay in community trust and legitimacy. Importantly, we also fnd  an immediate and striking decline in officer-initiated activity after the same incident in majority-Black neighborhoods. Conversely, White neighborhoods experienced a slight increase. This study reinforces and adds further context to a growing body of research that explains
how incidents of police violence can affect the actions of community residents and the police, including how we conceptualize and measure the concept of “de-policing.
