On January 23, 2012, the United States Supreme Court issued it’s decision in United States v. Jones. The Jones decision is noteworthy because it requires law enforcement to obtain a warrant when using a GPS device. A look at the facts in Jones is necessary to understand the Court’s reasoning.
The Government obtained a search warrant which allowed it to install a GPS tracking device on a car registered to Jones’ wife. The warrant authorized the GPS to be installed within 10 days of the issuance of the search warrant. The agents waited until the 11th day to install the device (after the expiration of the warrant). Then the Government tracked the vehicle’s movements for 28 days.
As a result of the tracking of the vehicle an indictment was issued charging Jones with drug trafficking and conspiracy. The trial court issued a split decision when Jones moved to suppress the evidence obtained by use of the GPS device, stating when the vehicle was parked at Jones’ house it was an illegal search but when it was on the public streets there wasn’t any expectation of privacy and therefore no illegal search. Jones was convicted and appealed.
