In a major victory for privacy, today in U.S. v. Jones the Supreme Court unanimously held that, “The Government’s attachment of the GPS device to the vehicle, and its use of that device to monitor the vehicle’s movements, constitutes a search under the Fourth Amendment.” The Court found that the government violated the Fourth Amendment, which protects American from unreasonable searches, when it placed a GPS device to Antoine Jones’s car and tracked his movements continuously for a month.
