Reducing Convenience Store Theft Using a Problem-Solving Model
Project Overview
The Glendale SPI team addressed thefts at Circle K™ convenience stores using a problem-solving model, named “Operation Not-so-Convenient.” Crimes were found to be clustered at Circle K locations (more than at other local convenience stores) and threatened the safety of both customers and Circle K employees. The team conducted geographic information system (GIS) analysis to map calls-for-service activity at Circle K stores with the highest frequency of calls to the Glendale Police Department, completed Crime Prevention through Environmental Design (CPTED) surveys of stores, and conducted surveillance of the most active locations. Ultimately, the SPI team developed a multifaceted response including recommendations for improved store operation and design, prevention efforts targeted at youth, and suppression operations focused on the most active locations. The team documented significant decreases in calls for service at three of the six high frequency call stores during the project period, resulting in the prevention of substantial costs to victims, the City of Glendale, and the police department.
Methods and Findings
Research Design
Pre/post analysis with multiple units and multiple control groups, interrupted time series analysis of convenience stores.
Findings
- Decline in calls for service in 5 of 6 target stores.
- 18% reduction in direct costs for officer response and estimated decrease of more than $1.9 million in victimization costs.
- Sustained reduction in 4 of 6 target stores (nearly 20% in calls for service overall, two years after the intervention).
