One major unresolved issue is the relationship between "the most dangerous leaker in American history" and WikiLeaks, an organization with an admitted antagonism toward the U.S. and a cozy history with the Kremlin.
Given WikiLeaks penchant for facilitating U.S. government leaks, its early involvement in the Snowden saga deserves scrutiny.
After the NSA contractor outed himself in Hong Kong on June 9, he parted ways with the journalists he met there and went underground.
On June 12, the same day he leaked specific details of NSA hacking in China to the South China Morning Post, Snowden contacted WikiLeaks. The organization subsequently paid for his lodgings and sent top advisor Sarah Harrison to help.
Harrison accompanied Snowden as he met with Russian officials (perhaps in the Kremlin consulate), and WikiLeaks bought his ticket to Moscow on June 23.
(Some suspect Russia and/or WikiLeaks contacted Snowden before June 12, but there is no clear evidence of that.)
Snowden and his closest supporters contend that he was on his way to Latin America when the U.S. government stranded him in Moscow, but there are several reasons to doubt that claim.
First, WikiLeaks founder Julian Assange told Janet Reitman of Rolling Stone that he advised Snowden against going to Latin America because "he would be physically safest in Russia."
Second, the U.S. revoked Snowden's passport by June 22, and the unsigned Ecuadorian travel document acquired by Assange was void when Snowden landed in Moscow.
WikiLeaks told BI that the Ecuadorian document was meant help Snowden leave Hong Kong. The organization has not explained why it would send the American to Russia knowing he was carrying a void passport and a bunk travel document.
On July 12, Snowden's Moscow lawyer Anatoly Kucherena explained that Snowden "is in a situation with no way out. He has no passport and can travel nowhere; he has no visa."
Third, even if Snowden had proper travel documentation, it's unclear if Russia's post-Soviet security services (FSB) would have allowed an NSA-trained hacker who beat the NSA vetting system and stole a bunch of intel to simply "pass through the business lounge, on the way to Cuba."
On August 1 Kucherena, who is employed by the FSB, explained why Russia granted Snowden temporary asylum: "Edward couldn't come and buy himself tickets to Havana or any other countries since he had no passport."
We would like to thank the Russian people and all those others who have helped to protect Mr. Snowden. We have won the battle--now the war.

Beyond its role in Snowden's getaway and its friendliness with Russia, WikiLeaks is also connected to three of the main people with access to the leaked NSA files. This fact does not necessarily tarnish their reporting, but it is intriguing in light of Wikileaks' deep involvement with Snowden.
Laura Poitras and Glenn Greenwald, two journalists contacted by Snowden and then given tens of thousands of documents by Snowden in Hong Kong, sit on the board of a foundation that launched in December 2012 to crowd-source funding for WikiLeaks.
Jacob Applebaum, a close friend of Poitras and lead author of at least one Der Spiegel story citing the Snowden leaks, is known as "The American WikiLeaks Hacker" and has co-authored others articles drawing from "internal NSA documents viewed by SPIEGEL."
Applebaum is not a journalist and does not hide his disdain for the NSA. This week he ended a talk - during which he presented never-before-seen NSA documents - by saying: "[If] you work for the NSA, I'd just like to encourage you to leak more documents."
Assange told the same audience to "join the CIA. Go in there. Go into the ballpark and get the ball and bring it out ... all those organizations will be infiltrated by this generation."
That is the same man largely credited with saving Snowden from extradition to the U.S. by sending him to Moscow. The 42-year-old Australian has also hosted a Kremlin-funded TV show. And his political party recently met with Syrian president Bashar al-Assad, who is staunchly backed by the Kremlin.
No wonder Greenwald told Rolling Stone that "Julian stepping forward and being the face of the story wasn't great for Snowden."
Snowden also hurt his own cause. Although he initiated an important debate, his statements and actions also pushed him beyond honest whistleblower.
All things considered, Snowden's affiliation with Assange and WikiLeaks raises a legitimate question: Is the fact that his life is now overseen by a Russian security more than an extraordinary coincidence?
Given that we still don't know how many classified documents Snowden stole or when he gave up access, that question should concern everyone.
