Defence arguments in the trial of former Army private Bradley Manning — who stands accused of a number of crimes for handing over classified documents to WikiLeaks, including a charge of “aiding the enemy” — finished Wednesday with testimony from Harvard law professor Yochai Benkler, who faced a number of questions from the judge and the prosecution about whether WikiLeaks is a media entity or not. Benkler’s answers highlighted some of the most contentious aspects of the trial, which in turn raise questions about what journalism and the media consist of in a networked age, and how we protect them.
