I hope you have read the election programme of the Labour Party...this is not socialism. It is Bolshevism run mad.

I have no intention of hiding who I am because I know I have done nothing wrong.

It's critical how we want to use these spy programs, these electronic capabilities, where we want to draw the line, and who should approve these programs, these decisions, and at what level, for engaging in operations that could lead us as a nation into a war.

The way the United States intelligence community operates is it doesn't limit itself to the protection of the homeland. It doesn't limit itself to countering terrorist threats, countering nuclear proliferation. It's also used for economic espionage, for political spying to gain some knowledge of what other countries are doing.

People at civil-liberties organizations say it's a sea change, and that it's very clear judges have begun to question more critically assertions made by the executive. Even though it seems so obvious now, it is extraordinary in the context of the last decade, because courts had simply said they were not the best branch to adjudicate these claims - which is completely wrong, because they are the only nonpolitical branch. They are the branch that is specifically charged with deciding issues that cannot be impartially decided by politicians.

We can plant bugs in machines. Once you go on the network, I can identify your machine. You will never be safe whatever protections you put in place.

Anyway, it's not true that the authorities cannot access the content of the phone even if there is no back door. When I was at the NSA, we did this every single day, even on Sundays. I believe that encryption is a civic responsibility, a civic duty.
