Dump all the documents
He should dump all the documents, not just a few redacted version, everything. What does he have to lose at this point? Wikileaks, PasteBin, etc, plenty of places to put them. They're going to call him a traitor and lock him up forever at the first chance.
Other leakers are still coming forward, the NYT has an article from an unidentified ex NSA man explaining how the NSA have created a secret parallel system of law, created by the FISA court expanding its remit to compare with the Supreme Court.
This is a video about the release of the Pentagon papers (this same thing in 1970s), how they came to be leaked by a contractor, how a brave politician found a way to read the complete papers into public record, making them legally public, how even then Nixon tried to bully newspapers to prevent them printing them.
It was the *complete* Pentagon papers. It didn't do the US harm, it woke them up before it was too late.
Nixon was a crook and the Pentagon papers revealed how fake the Vietnam war was. The people involved in the leak, then vilified as traitors, today are universally viewed as heroes.
