Getting a fair trial is really not the issue since he clearly broke the law.
It all hinges on PR. If the government was able to smear him enough that the majority of people considered him a traitor, then they would do their damnedest to make an example out of him. On the other hand, if people came to see Snowden in a positive light they wouldn't dare martyr him. Given the general apathy that we've seen from so many Americans (even Ira Glass from This American Life basically said "meh, what do I have to hide?"), I can't help but to sadly feel he made the right choice.
