Journalists and their sources face increasingly invasive surveillance tactics. Digital security is often compromised, and a major new UN study of 121 countries' legal source protection frameworks has found that they are out of date and need strengthening in many cases.

Julie Posetti, who authored the report, spoke at the International Journalism Festival in Italy about protecting sources in the digital age, just days after the Panama Papers story broke.

This episode features her panel at the festival, where she spoke alongside journalist at Der Spiegel Marcel Rosenbach, director of the Knight Center for Digital Media Entrepreneurship Professor Dan Gilmore, and freedom of information campaigner and journalist Heather Brooke.
