A large municipal policing agency housing one of the oldest K9 programs in the USA suddenly terminated the program at the close of summer 2020. We exploit this change as a natural experiment to test three hypotheses related to rates of injuries (officer and suspect) and resisting arrest. We use Bayesian modeling in an interrupted time series analysis to measure the immediate and long-term effects of the K9 apprehension program’s suspension on our hypotheses. The sudden suspension of K9 apprehension was not associated with a statistical increase in officer or suspect injury, or suspect resistance, during felony arrests.

Ph.D. Candidate

I am a Ph.D. candidate in Political Science at the University of Utah and a National Institute of Justice LEADS scholar. I study policing and criminal justice policy. I am particularly interested in public perceptions of police use-of-force and the criminal justice system, investigative techniques in sexual assault cases, and crime deterrence policy.
