For Garzón, defending Assange means protecting the cause of transparency and freedom of information in a world transformed by the technological revolution of internet. The stakes are: our right to information, freedom of speech, freedom of the press and their ability to check the powers.
WikiLeaks earned a lot of criticism for its editorial decisions. However many analysts agree that arresting Assange would be a threat to the First Amendment. And a Wikileaks prosecution will endanger the future of journalism, because it could set a dangerous precedent for other media organizations.
The investigation of Assange and Wikileaks dates back to 2010 but prosecutors struggled with the question of whether the First Amendment protected Assange. Now the prosecution reportedly has found a way to proceed but offers no details on the nature of the charges they plan to file. In short, what Wikileaks is doing is unacceptable to (US) authorities. It puts at risk their national security, it undermines their foreign policy interests - they want Assange stopped. If Assange is arrested he may face life imprisonment or worse, the Death Penalty.
