I had direct experience in every aspect of interrogation and intelligence in the so-called “war on terror.” From producing intelligence through interrogation to assessing it to seeing policies made from it, I was there.

It does not work, it is unnecessary, it is illegal, it betrays our ideals and our nation’s laws. There is no practical, legal, moral, or utilitarian argument in favor of torture. We don’t need it, and it betrays who we seek to be. No fine-tuning of the law is necessary to justify it — ever.
