Assange didn't really do anything wrong. He just shared information that governments want secret because they know it's bad. It's not like he was doing it to cause economic damage or terror or even endangering lives. At worst a few people who really deserved it were brought to justice or fired. They've just been desperate to arrest him for something that won't turn into another wikileaks scandal.

There are traitors, but that involves being a citizen and in the military or government and stealing or revealing secrets kinda like Snowden or Manning. Or definitely an officer like Benedict Arnold.
