When the Arlington, Texas, Police Department (APD) began using the National Incident-Based Reporting System (NIBRS), its understanding of local crime trends and the factors driving them was transformed. NIBRS has allowed APD to better identify the precise offences driving changes in more aggregated offence categories and to respond to crime more effectively. With larceny-theft as an example, we describe APD's NIBRS transition, how it altered crime control strategy, and how it impacted APD's responses to crime. This description serves as an example to the field of the value of NIBRS for developing effective crime prevention strategies and tactics. We also analyse APD's NIBRS data for the years 2017 and 2018 to demonstrate other possible uses of these data that would allow law enforcement agencies to better understand the factors driving crime in their jurisdiction. We explain how this understanding can lead to more targeted and effective policing strategies and tactics.
