The meeting took place in Snowden's Hong Kong hotel room after he had fled the United States with a trove of classified information which revealed a 'systematic surveillance of innocent citizens', and which he was now about to reveal to the international press for public scrutiny and judgement.
What ever the final legal opinion of his actions, or one's own opinion of Snowden (traitor, idiot, whistleblower), he expressed his intentions as well meaning:
“It’s important to send a message to government that people will not be intimidated.” 
The documents he provided indicated that the same method by which the National Security Agency had searched for, identified, and secured potential enemy combatants also scooped up "the bulk communications data of millions of American citizens, and regardless of whether they were suspected of any wrongdoing." 
Perhaps all would be well and good if that data was immediately disposed of some kind of secure erasure, but as Oregon Senator Ron Wyden would later explain to the Guardian:
"Once Americans' communications are collected, a gap in the law ... allows the government to potentially go through these communications and conduct warrantless searches for the phone calls or emails of law-abiding Americans." 
On June 7th, two days after the initial published report of Snowden’s leaks, both The Guardian and The Washington Post reported that “the NSA is accessing the systems of US internet giants including Google and Facebook, and collecting data under a previously undisclosed surveillance programme called Prism. The programme allows officials to collect material including emails, live chats and search histories." 
Additional NSA documents leaked by Snowden indicated that the NSA had also extended its practice of casting a wide digital net on both the leaders and citizens of several allied nations.
For instance, the agency had been exposed as having tapped German Chancellor Angela Merkel's cell phone for a decade. In another instance, the NSA collected some 70 million digital communications in France, in just one 30-day period between Dec. 2012 and Jan. 2013. Needless to say, leaders across the globe expressed outrage. 
Certainly, both wire and web tapping have long proved a valid and acceptable means to protect the populace from criminal endeavor. However, the legal interception of electronic communications has typically required a warrant and is usually limited to those communications that meet a stringent standard of relevance to a specific case.
In fact, in the United States, in order to obtain a warrant, the FISA [Foreign Intelligence Surveillance Act] court typically requests the production of records "pertaining to a specific named target who is suspected of being an agent of a terrorist group or foreign state, or a finite set of individually named targets."
Snowden has since been granted asylum in Russia, although his residence in that country is limited to a year. Meanwhile back in the United States, mention of the one time Booz Allen cyber spy continues to spark heated discussion, and Snowden is alternately described as a whistleblower by his supporters, or accused of being a traitor by those who consider his actions a terrible betrayal against the nation.
How this story finishes is anyone's guess at this point.
In the meantime, Edward Snowden’s explosive revelations and the ensuing international clamor they caused have resulted in the Tap-Tap Tapping of Internet Surveillance being named as the 2013 Critical Noise Sound of the Year.
