Inside Story Americas - Public safety or privacy intrusion?

Edward Snowden's revelations about the US National Security agency's Internet and telephone monitoring programme have provoked debate at home and abroad. We ask if it is acceptable or not for the US government to access American citizen's personal data. Inside Story Americas, with presenter Shihab Rattansi, discusses with guests: Peter Swire, Law Professor at Ohio State University and Chief Counsellor for Privacy in the Clinton administration; Julian Sanchez, researcher on privacy and technology at the Cato Institute; and Karen Reilly, research director for the Tor Project which provides software that allows users to access the Internet anonymously.
