Why should he be punished at all if what he did was right?
If anything he should be praised. We need more people to be willing to speak out.
Chelsea Manning took her punishment. That is the point of martyrdom-that the victim suffer for the greater good.
What kind of logic is that? You want people who did nothing wrong to be unjustly punished just so that they can then claim to be martyrs? Isn't the world better if we don't actively try to create martyrs?
I think what he means is that while he does not believe that what he did with regard to espionage was wrong, but rather it is the fact that he fled to Russia. That may be what he believes Snowden ought to be punished for.
