Torture and argument

I'm against torture. I think it's vicious, and there's no reason to believe it's a good way of getting reliable information. It has bad side effects, like torturers coming home from the war and getting jobs with police and security.

However, and as happens so often, not everyone agrees with me.

I would like more people to agree with me on this issue, and saying yet again that torture is bad probably isn't going to help much. Pro-torture and anti-torture people have really different moral intuitions on the subject.

So, does anyone know of someone who believed torture was legitimate, then changed their mind to be opposed to it?

I'm especially interested in what changes the minds of people who have no experience with torture, since they're the vast majority.

Also, there were a couple of talk show hosts who let themselves be waterboarded, and concluded that yes, it's torture. Anyone know whether they also concluded that torture is bad?
