Is GPS Tracking Legal for Law Enforcement?

In the US vs. Pineda-Moreno decision, the US Court of Appeals for the Ninth Circuit ruled that Law enforcement agents can legally place a GPS device on an individual’s car without their knowledge and without a warrant from a judge. Attorneys and co-hosts Bob Ambrogi and J. Craig Williams, welcome Orin S. Kerr, contributing blogger to the Volokh Conspiracy and Professor of Law at the George Washington University Law School, to discuss the legality of GPS tracking in light of the Fourth Amendment, privacy rights, the role of technology and the possibility that this case and others like it will reach the Supreme Court.
