I have zero knowledge as far as sentence's go. So with that said, how is being required to only server 1/3 of a sentence brutal? What am i missing?
Well, for one, he's transsexual, which may or may not indicate he's less of a threat to society. If he's not a threat to society, and won't do what he did again, then it seems like the motive is to make an example of him.
That being said, I don't think Manning is (or has been) a threat to society at all. Perhaps he should have been a little more careful about what he released but I feel he's done the world community a net good by exposing war crimes, etc[0].
I do agree he is being made an example of, and this sentence and his treatment is intended to be a signal and a warning sign to would-be leakers. I hope they still come forward and behave more like Snowden than Manning.
