Assange is just a dude who published information he was given. That American authorities and media now call for his blood is somewhat laughable, especially the news agencies that take this position. Such choice irony, demonizing a man for providing unbiased information to the public as they completely fail in their supposed duty to provide unbiased information to the public.
I don't think Assange is any kind of hero, though. The real hero is Bradley Manning, who's been treated like a terrorist/enemy combatant instead of an American citizen for the "crime" of whistle-blowing on a horrendous act. He did the right thing, and sits in a cell for it, as his name is dragged through the mud of public opinion.
In my book Manning is an anarchist. If he operated in any other venue you might be right but the military can't tolerate anarchy.
