Snowden appeared via satellite link in the Australian city of Melbourne last night, live from Russia where he resides under temporary asylum after leaking classified documents that revealed the extent of the modern global western government intelligence apparatus.
The AFP Friday raided the office of Labor power-broker and former comms minister Stephen Conroy and the home of a staffer of shadow communications minister Jason Clare.
Snowden cites the nation's "drag net" data retention and anti-whistleblower laws in which citizen metadata is retained for two years, and those who leak national security documents may be imprisoned.
Former Pentagon investigator John Crane has today told The Guardian how the agency became a trap for whistleblowers, including forerunner NSA leaker Thomas Drake.
"If someone is saying I don't care about the right to privacy because I've got nothing to hide' that's no different to saying 'I don't care about freedom of speech because I have nothing to say'," Snowden says.
Snowden also spoke of the power of metadata, suggesting it is more valuable than content because it provides the investigator with similar intelligence while often foregoing the need to acquire warrants.
