You make it sound like Snowden is trying to flee justice, but he has made clear multiple times that he intends to return to the US if he is allowed to defend himself before a jury in an open court, something that the Espionage Act prevents him from doing. You’re not the only person who “believes strongly in the rule of law.”

And by the way, when exactly did Snowden “go beyond the limits?” As far as I’m aware, he made sure to hand over every copy of the documents he possessed to professional reporters so that every disclosure made was legitimately in the public interest.
