Most people don't know what goes on in the intelligence services. Certainly I had very little idea what went on in GCHQ. For me it was a job, a chance to use my languages.

I work for the British people. I do not gather intelligence so the government can lie to the British people.

If my own country is subverting the rule of law and sending its own citizens, its military, into harm's way on the basis of lies and propaganda, I would argue that being a patriot is calling out those lies and saying, ‘No, you don't send our military into harm's way with no legal justification.'"

I grew up in Taiwan, which was a military dictatorship.

Without the way, there is no going; without the truth, there is no knowing; without the life, there is no living.

I meet people in my daily life, people who seem to experience some change and some growth on a personal level, and that gives me hope.

Over the years, my relationship with God has changed my life for the better - it's grown me up, given me a sense of purpose, and grounded me in my identity.

Experience shows that the reliance on illegal, immoral, and inhumane interrogation techniques is universally a very poor choice.
