Dilbert cartoonist Scott Adams writes in the Washington Post that he used to believe torture could be an effective interrogation tool, but now he has doubts. If torture is not more effective than available alternatives, he argues, we need not debate whether it can be justified, as the answer would always be no.

The burden is on torture's proponents to produce some evidence that torture makes sense as a policy. I don't rule out the possibility that it can be effective in some cases, but if it's being done in my name, I want some frigging evidence that it works.

Then we can talk about morality.
