Sure, it's a judgement call and whistleblowers have to do the best they can. If they make the wrong decision they're in the second category, so they have to decide if it's worth the risk. If they reveal the secrets to lawyers they're still breaking the law.

I agree that from what I've seen, Manning is on the civil disobedience side. I wish he had changed voters minds more than he apparently did.

Snowden had evidence of clearly illegal activity. There was a lot more mixed in, but it wasn't practical to separate it. Secret abuse of power is dangerous enough that I think that should be acceptable.

If we don't have practical protection for whistleblowers, we might as well not bother putting limits on government power at all. Based on what's happened to whistleblowers who went through official channels, it's clear that that approach doesn't work at all, and I don't know why anyone should expect it to work.
