Prior research has sought to identify appropriate mechanisms that can effectively control police officers' decisions to use deadly force. Using data from Philadelphia for a period of more than two decades, this article employs interrupted time series analysis (ARIMA) to examine the impact of two changes in administrative policy on monthly levels of deadly force in Philadelphia. Findings support prior deadly force research suggesting that administrative policy can be an effective deadly force discretion control, but the Philadelphia experience indicates that formal policy can be outweighed by the personal philosophies and policies of the chief, and that its impact is limited to elective encounters.
