A recent Pew Research Study, found out that Americans are divided on the issue of torture...
"Amid intense debate over the use of torture against suspected terrorists, public opinion about this issue remains fairly stable. Currently, nearly half say the use of torture under such circumstances is often (15%) or sometimes (34%) justified; about the same proportion believes that the torture of suspected terrorists is rarely (22%) or never (25%) justified."
I'm partial to Elie Wiesel's opinion:
"Torture is always wrong, because the tortured person dies more than once."
