I mean there's enormous pressures to harmonize freedom of speech legislation and transparency legislation around the world - within the E.U., between China and the United States. Which way is it going to go? It's hard to see.

Intelligence agencies keep things secret because they often violate the rule of law or of good behavior.

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.

If journalism is good, it is controversial, by its nature.
