Abstract
Police departments rely on administrative rules to set organizational priorities and
establish systems of accountability. To that end, several departments require officers
to submit data describing every traffic stop they conduct as a way of tracking officer
activity and identifying any race-based disparities. This paper draws on an analysis of
San Diego Police Department traffic stop records, as well as officer survey and
interview data, to examine the validity of the traffic stop data gathered and the
compliance-related motivations of officers. Findings indicate a 19 percent error
rate in stop data submitted between 2014 and 2015, amidst evidence of substantial
underreporting. Qualitative data suggest that officers see the policy as redundant and
an infringement on more pressing aspects of their job. They doubt the ability of
external stakeholders to interpret the data objectively and report a loss of morale,
largely attributed to the perception that their actions are inaccurately racialized.
