Court says police need a warrant to track vehicles via GPS
A federal appeals court has ruled that the government must obtain a warrant to attach a GPS unit to a car.
The Third Circuit Court of Appeals held in a two-to-one decision that attaching a GPS device to a car without a warrant is an "unreasonable search," and therefore unconstitutional. The ruling extends a recent Supreme Court ruling, which found that GPS tracking constituted a search but did not rule on whether it's reasonable to conduct such a search without a warrant. American Civil Liberties Union Staff Attorney Catherine Crump, who had argued before the panel, called the decision "a victory for all Americans because it ensures that the police cannot use powerful tracking technology without court supervision and a good reason to believe it will turn up evidence of wrongdoing."
