Search warrants: tracking devices.

Existing law prohibits, with exceptions, the use of an electronic tracking device to determine the location or movement of a person. Under existing law a violation of these provisions is a misdemeanor. Existing law states that these provisions do not apply to the lawful use of an electronic tracking device by a law enforcement agency. Existing decisional law, in the case of U.S. v. Jones, holds that the attachment of a Global Positioning System (GPS) tracking device to a vehicle and the use of the device to track the vehicle is a search within the meaning of the Fourth Amendment to the United States Constitution.
