摘要

The study explores the association between actual and perceived police effectiveness in solving homicides and community members’ willingness to cooperate in homicide investigations. Using original survey data collected from five Chicago neighborhoods with high homicide rates and varying clearance rates, the study analyzes the impact of both actual and perceived homicide clearance rates on the likelihood of individuals cooperating in a homicide investigation. The research focuses on two forms of cooperation: calling the police after witnessing a homicide and providing information about a suspect associated with a homicide. Results from multinomial logistic regression analyses indicate that higher actual and perceived clearance rates significantly increase the probability of cooperation. Importantly, the study highlights that community perceptions of police effectiveness are critical in shaping cooperative behavior, suggesting that improving both real and perceived police efficacy could enhance homicide clearance outcomes. The study contributes to existing theories of police legitimacy by offering empirical evidence on the role of perceived police effectiveness in fostering cooperation in the context of homicide investigations. Moreover, the study emphasizes the importance of community-centered approaches to improving homicide clearance rates, particularly in racially and ethnically diverse neighborhoods disproportionately affected by violence.
