questioning whether the trial of the mastermind behind 9/11 will be 'humiliating' for America = pathetic.
The defendant has confessed to the crime and is being tried on American soil.
The prosecution has tonnes of evidence on this person. The fact he was waterboarded is merely a (bonus) footnote. He's likely to be given the death penalty too.
If anything, this shows how legally backward we and the rest of Europe are when compared to the US.
