A defendant, Antoine Jones, was under suspicion of trafficking narcotics. To investigate the defendant, plaintiff government agents installed a GPS tracking device on the undercarriage of a vehicle registered to the defendant's wife while it was parked in a public parking lot. For the next 28 days the government used this device to track the vehicle's movements. In court, the defendant sought a motion to suppress evidence obtained through the GPS device, alleging that it violated the Fourth Amendment. The court found that admission of the evidence obtained by warrantless use of the GPS device by the government agents violated the Fourth Amendment, and constituted an unreasonable search. Do you agree with the court's decision on appeal? Why or why not? Based on your reading in this chapter, what evidence would the court need to determine whether a violation of the Fourth Amendment existed? United States v. Jones, 132 S. Ct. 945 (2012).
