The reason this talking point comes up, of course, is because the WikiLeaks founder is besieged by powerful forces who are attempting to imprison him for publishing inconvenient facts about them, and his defenders often voice their concerns about what this means for the future of press freedoms. The completely baseless claim that Assange is “not a journalist” is used in an attempt to defuse the argument that his prosecution by the US government could lead to the same fate for any news media outlet which publishes leaks on the US government anywhere in the world. If he’s not a journalist, then his prosecution sets no precedent for real journalists.
This argument, if you can call it that, is fallacious for a number of reasons. For starters, as The Intercept‘s Glenn Greenwald explained last year, there’s not any legal distinction in the US Constitution between news media outlets like the New York Times and an outlet which solely focuses on publishing leaks. If you set the precedent with any publisher, you’re necessarily setting it for all of them.
