I can remember only a small handful of instances in which I talked about politics with my parents. I remember my parents telling me that Daniel Ellsberg was a hero when I was six years old.

Even if torture works, it cannot be tolerated -- not in one case or a thousand or a million. If their efficacy becomes the measure of abhorrent acts, all sorts of unspeakable crimes somehow become acceptable. I may have found myself on the wrong side of government on torture.
