I know Dershowitz claims that the judge had anti Israel bias. Then again Desshowitz is not above lying for his clients and Pollard is not an exception. I once saw a debate with Joe DeGenova, who prosecuted Pollard. DeGenova kept asking him about a memo that was used at the trial. Dershowitz kept saying he is not allowed to say if he saw it. Obviously he did see it and could not refute it.
If Dershowitz officially represented Pollard at trial, that’s news to me. I believe Pollard’s attorney at trial was named Hibey.
Later, on appeal, Ted Olsen (husband of the late conservative attorney and writer Barbara Olsen), who later became Solicitor General under W, represented Pollard. It turned out that Pollard’s conviction would have been overturned and he would have had a new trial had not Ruth Bader Ginsberg ruled against him on a procedural matter on a DC Circuit 3-judge panel back in the late 80s or early 90s.
Dershowitz’s role in the case was limited to commentator and pundit, to the best of my knowledge.
Please correct me if I’m mistaken.
