The Structure of Officer-Involved Shootings: Investigating the Social Transmission of Firearm Use


This study will examine how officers' informal networks and working relationships shape behaviors and attitudes toward firearm use.




This project seeks to determine whether the social structure of police networks enables or constrains the social transmission of officer-involved shootings.


This project will collect longitudinal network data from all sworn officers in one of the 50 largest police departments, to address the following objectives:

  • Analyze the social structure of a police department, and assess ethnographic claims that excessive force tends to cluster among subsets of tightly knit officers; and
  • Investigate whether interactions between officers promote the diffusion of behaviors and attitudes associated with officer-involved shootings to identify the exposure factors that both increase and mitigate the risk of involvement in firearm use behaviors.


Much ethnographic research documents the role formal and informal associations among officers play in influencing both individual actions and institutional culture. The current study will address the untested hypothesis that officers' networks enable or constrain the likelihood of firearm use, and seeks to provide actionable data to inform policy initiatives to reduce officer-involved shootings.
