(video link)On June 13, 2017, Mark Jaffe is set to appear before the 9th US Circuit Court of Appeals in San Francisco to argue on behalf of his client, journalist Matthew Keys. And at the most recent Ars Live event, Jaffe spoke to David Kravets and I about this case and broader issues around what it's like to defend accused hackers. As Ars reported in August 2016, the 29-year-old journalist began his two-year sentence in Atwater, California, about 120 miles east of San Francisco.
