This report describes a randomized controlled evaluation of a TPP intervention implemented in Anne Arundel County, Maryland. The intervention, called Operation CheckOut, aimed to reduce drug problems at hotels and motels by fostering trusted partnerships between police and hotel staff. Officers from the Anne Arundel County Police Department (AACOPD) conducted four in-person visits between August 2022 and May 2023 to a randomly selected group of hotels. During in-person visits, officers engaged in a scripted procedural justice dialogue with hotel managers, delivered educational materials, identified legal responsibilities, and provided a dedicated email address that functioned as a “tip line” to report problems or suspicious activity directly to the Operation Check-Out team. The intervention was designed as a partial replication of Operation Galley, a TPP intervention iv implemented by the Queensland (Australia) Police Service in 2017 (Mazerolle et al. 2018). The goal of the intervention was to bolster intelligence, investigations, and enforcement actions; reduce crime and disorder; and improve perceptions of police.
