This study uses the narratives from affidavits for warrantless arrest from two police agencies to examine the strategy of using pretextual traffic stops for drug interdiction. Officers stop a vehicle, arrest the driver on a minor offense, and then use vehicle searches to transform minor infractions into felony drug arrests. The case study illustrates how discretion, profiling, and aggressive use of search and seizure come together. The drug convictions initiated through traffic stops were overwhelmingly discretionary and seemingly pretextual, and the arrests that led to findings of contraband were themselves discretionary and mere pretexts for conducting extensive searches of automobiles and persons.
