The biggest question was always why. His supporters claimed it was about war crimes, but it couldn't be that by sheer breadth of unrelated information he leaked.
The motive of getting back at the Army at least made sense, but he makes fairly clear that his NJP was the last thing that happened, not the first.
So an idealistic quandary? Perhaps he wasn't yet sufficiently jaded but he had to have known nothing would change going that route. By leaking indiscriminately, at such sheer scale, and information that's not actually pointing to a war crime or other government malfeasance he opens the government up to many defenses against what the information contained.
But either way, he said he wouldn't. He said further that if he did uncover evidence of wrongdoing that he would report it properly.
I mean let's put it a different way. You provide a SaaS/PaaS /what-have-you to a Fortune 50 enterprise.
What, ethically, would stop you from snooping at their data and leaking it? If you contort your logic enough, as happened to Manning, you could easily flip it around entirely to claim that you had a moral imperative to look for wrongdoing in the emails and documents of these large multi-nationals that affect so many lives across the world.
Presumably we can rely on the tech startups incubated at HN not to do this, but why? Why would it be OK for Manning and not your cloud provider? Why would it not be OK for the cloud provider and OK for Manning?
I guess in the end that's what I wonder most about, even now. Why?
I and probably millions of others have had the opportunity "to start a public debate" if that's all we were worried about, but we didn't. Why did Manning? L'appel du vide? The stress of being LGBT in the military? And how can we balance the need for transparency in military and government with the very real need for INFOSEC to protect the same?
