Justifiable?

Brother Mark found this (admittedly unscientific) survey on CNN, indicating that almost half the folks who responded think that there are circumstances in which torture is justified during interrogation.

I gotta tell you, both my gut reaction and my thoughtful, prayerful consideration agree on a response.

Ew.

Seriously, is there anyone out there who can offer an argument? Please feel free to comment, because I just don't understand this.
