In 2004, law enforcement officers began investigating Antoine Jones, a Washington, D.C. nightclub owner, for suspected drug trafficking. After gathering information through stakeouts, cameras, and a wiretap on Jones’ phone, the officers obtained a warrant to place a Global Positioning System (GPS) tracker on Jones’ wife’s car, which Jones possessed and used regularly. However, the officers failed to comply with the precise terms of the warrant, making the installation and use of the tracker warrantless. The officers tracked the car’s every movement, twenty-four hours per day, for an entire month. The data linked Jones to a stash house containing a great deal of cash and cocaine.
