Why One Expert Says Edward Snowden Deserves Clemency

"GREENE: So make the case for me, if you can, that Edward Snowden deserves some kind of clemency.

GRANICK: Well, we would not know what our government is doing, we would not know the extent to which they spy on us, were it not for Edward Snowden. There were whistleblowers before him about the NSA, but the documents that Snowden took proved the truth of what those whistleblowers and what Edward Snowden was saying. And only because we have those documents, our government has had to come clean about its practices."
