The use and effectiveness of investigative police stops

Abstract

ABSTRACT This article asks if investigative police stops (1) help officers find contraband, and (2) serve as a bulwark against violent crime. We focus on the experiences of Fayetteville, North Carolina, which in 2012 mandated that police officers obtain written permission from motorists before conducting searches absent any probable cause. The effect of these mandates was a dramatic reduction in the use of so-called “consent searches.” Using traffic stops data available from the North Carolina Department of Justice, we show that after these reforms went into effect officers made fewer overall searches, but contraband continued to be recovered at pre-reform levels, indicating a reduction in low-quality searches with minimal substantive impact. Moreover, we find that homicide rates are statistically indistinguishable between the pre- and post-reform periods. Thus, Fayetteville local government was able to implement community pleasing police reforms without jeopardizing community safety.
