Consider a fact pattern that takes place every day, all across the country: a police officer stops a motorist for a traffic infraction, runs the motorist’s license through a computer database and finds nothing exceptional, and returns the driver’s license and registration, perhaps along with a warning or a citation. The officer then asks the driver for consent to search the driver’s car. The driver consents and the officer finds drugs. Did the officer do anything wrong in this situation? Are the drugs subject to suppression? The answers depend on whether the traffic stop ended when the officer returned the driver’s license. As a recent case shows, that can be a complex determination.
