I’m an attorney (reformed prosecutor, actually) and Dershowitz used to nauseate me. However, if I were accused of a crime I didn’t commit he’s at the top of the list of the people I’d want next to me in the Courtroom.
What Dershowitz is absolutely implacable about is the idea that the government is bound by its own rules. He is very strong on the Rule of Law. Might have something to do with his Jewish historical perspective; he knows what happens when a government no longer recognizes the Rule of Law.
Dersh is also extremely vocal about infringement of free speech on college campuses, particularly the hypocrisy of warmly embracing left-wing freaks like Ward Churchill while conservative or even moderate speakers are often banned. Alan isn't nearly so accepting of political correctness as many of his fellow academics would have him be.
