Are you arguing that Dershowitz took Amanda Knox's side because nobody else would, or because he's an investigative genius who objectively evaluated the case and came to the conclusion the Italian authorities were completely misguided?

Was it a moral issue with him, or did he want publicity?

John Douglas took her side out of deep moral conviction that an injustice had occurred.

The distinction seems important.

I promise I'm not trying to be a smart ass but what is the relevance? He's still going to provide cover to Republicans to vote against removing a dangerous president. He's misusing his "gifts" (if "contrarianess" is a gift).
