Federal Judge: No Warrant Needed to Use GPS Tracker
A federal judge in Utica, NY, ruled that police officers do not need a warrant to secretly attach a Global Positioning System device to a suspect's vehicle, and use that to track the suspect's movements. The judge said that a suspect traveling on a highway has no reasonable expectation of privacy, so his civil liberties are not violated by this secret tracking.
