Ruling on GPS Tracking Devices

djembe2k writes "Score one for civil liberties. The NY Times is carrying a wire story (free reg. required, yadda) reporting that the Supreme Court of Washington state ruled today that a warrant is required by police to use GPS tracking devices to track suspects. A warrant actually was obtained in the case at hand, but the prosecutors argued that they hadn't really needed one, and they lost on this point. Here's the full text of the ruling."

The opinion addresses your question:

[Note: the Court of Appeals is the lower court being overruled here]

The Court of Appeals also held that use of the GPS devices was merely sense augmenting, revealing information that Jackson exposed to public view. The court noted that law enforcement officers could legally follow Jackson on his travels to the ministorage compartment and the two gravesites. We do not agree that use of the GPS devices to monitor Mr. Jackson's travels merely equates to following him on public roads where he has voluntarily exposed himself to public view.

It is true that an officer standing at a distance in a lawful place may use binoculars to bring into closer view what he sees, or an officer may use a flashlight at night to see what is plainly there to be seen by day. However, when a GPS device is attached to a vehicle, law enforcement officers do not in fact follow the vehicle. Thus, unlike binoculars or a flashlight, the GPS device does not merely augment the officers' senses, but rather provides a technological substitute for traditional visual tracking. Further, the devices in this case were in place for approximately two and one-half weeks. It is unlikely that the sheriff's department could have successfully maintained uninterrupted 24-hour surveillance throughout this time by following Jackson. Even longer tracking periods might be undertaken, depending upon the circumstances of a case. We perceive a difference between the kind of uninterrupted, 24-hour a day surveillance possible through use of a GPS device, which does not depend upon whether an officer could in fact have maintained visual contact over the tracking period, and an officer's use of binoculars or a flashlight to augment his or her senses.
