I'm fully aware of what happened, stop trying to play it off like you're on the intellectual high ground. You were the one who are suggesting that Graner and England know the benefits of torture but there's a fundamental flaw in that argument.
THEY WEREN'T TORTURING FOR INFORMATION. There was no military motivation for what they did, they just did it. Torture is never the way to go. John McCain knows this and
Matthew Alexander knows even more than McCain, Graner, England, Rumsfeld, Cheney or anyone else in the Bush Administration does.
