"The Drake case collapsed in spectacular fashion when the judge found that the information Drake possessed was completely unclassified, and had only been marked otherwise after it was seized from his home."
I doubt he would have had assassins on his trail, but he would have been put through the legal system the same way Manning was.
Also consider the court of public opinion -- there's enough of an uninformed mass who think this is a scumbag who gave American secrets to China and Russia that an administration can bend the laws quite a bit and get away with it.
I don't know which law you are consulting for the definition of "torture," but if solitary confinement is torture then our system hands it out for many people less famous and glamorous than Snowden all the time, without much of any outcry. And this outcry seems to be confined to certain political figures, not just any prisoner caught with a shank.
