The more important question is: did the US murder innocent civilians? It's not about the cables or the messenger or the medium or the style and presentation, it's about the murdered innocent civilians.

The debt we owe Manning for exposing the fact that the US murdered innocent civilians far outweighs the damage she did by releasing the cables. The prosecution couldn't identify anyone who was harmed, beyond those innocents harmed by the US government machine guns, which wasn't Manning's fault.
