When it comes to political engagement, I'm not a politician - I'm an engineer.

We have these traditional political parties that are less and less responsive to the needs of ordinary people, so people are in search of their own values.

When we have some horrible terrorist attacks happen in some country we see in the recording that follows, that the intelligence community already knew about these people in advance. We know that these countries were involved in intelligence sharing premiums, that they benefited from mass surveillance, and yet they didn't stop the attacks. Yet at the same time we immediately see intelligence officials running to the newspapers and claiming that we need more surveillance, that we need more intrusion, that we need more expense of powers because it could have stopped an attack.

We need to think about encryption not as this sort of arcane, black art. It's a basic protection.

Russia recently passed a law - I think a terrible law - which says you have to store all of the data from Russian citizens on Russian soil just to prevent other countries from playing the same kind of legal games we're playing in this Microsoft case.

I understand that I will be made to suffer for my actions, and that the return of this information to the public marks my end.

The work of a generation is beginning here, with your hearings, and you have the full measure of my gratitude and support.
