Torture memos

[Undertoad]

...reportedly found that the DoJ attorneys who wrote the torture memos may have deliberately slanted their legal advice to provide the White House with the conclusions it wanted...

We await this finding. If they just wrote opinions, how could one know whether it was deliberate? It seems to me that proof would require:

A) Word had to be passed from the WH on what conclusions they wanted. "We need you to create an opinion that permits the harshest levels of interrogation possible, although that may be unlawful. We will make sure you aren't held accountable."

or

B) Evidence that the DoJ attorneys had a different opinion before being asked. "Attorney X published an opinion ten years ago that stated unequivocally that waterboarding is torture."
