Senators on torture in Zero Dark Thirty

Senators McCain, Feinstein, and Levin write to Sony Pictures regarding the depiction of torture in Zero Dark Thirty:

Recent public opinion polls suggest that a narrow majority of Americans believe that torture can be justified as an effective form of intelligence gathering. This is false. We know that cruel, inhuman, and degrading treatment of prisoners is an unreliable and highly ineffective means of gathering intelligence.

The use of torture should be banished from serious public discourse for these reasons alone, but more importantly, because it is a violation of the Geneva Conventions, because it is an affront to America's national honor, and because it is wrong.
