"Knowledge has always flowed upwards to bishops and kings, not down to serfs and slaves." — Julian Assange

Journalism should be more like science. As far as possible, facts should be verifiable. If journalists want long-term credibility for their profession, they have to go in that direction. Have more respect for readers.

In my role as Wikileaks editor, I've been involved in fighting off many legal attacks. To do that, and keep our sources safe, we have had to spread assets, encrypt everything, and move telecommunications and people around the world to activate protective laws in different national jurisdictions.

We get information in the mail, the regular postal mail, encrypted or not, vet it like a regular news organization, format it - which is sometimes something that's quite hard to do, when you're talking about giant databases of information - release it to the public and then defend ourselves against the inevitable legal and political attacks.

I had had a lot of experience in bringing the Internet to Australia, and I saw that knowledge in the hands of people achieves reform.
