I don't think this should be reduced to her original actions. She was sentenced as a consequence of them, she served 7 years until the rest of the sentence was communted by Obama.

So the real question is: was it appropriate to throw her back into prison, under very harsh conditions, just to force a statement from her. I think there is very good reasons to doubt that, independant of the stance about her original actions. From that perspective, I think her release is good news.
