IN November, the Supreme Court will hear arguments in a case that could redefine the scope of privacy in an age of increasingly ubiquitous surveillance technologies like GPS devices and face-recognition software.
The case, United States v. Jones, concerns a GPS device that the police, without a valid warrant, placed on the car of a suspected drug dealer in Washington, D.C. The police then tracked his movements for a month and used the information to convict him of conspiracy to sell cocaine. The question before the court is whether this violated the Fourth Amendment to the Constitution, which prohibits unreasonable searches and seizures of our “persons, houses, papers, and effects.”
