Two completely different cases, but you’re right. Dershowitz has a brilliant legal mind.
He must be up in years by now. A Boston radio guy whose wife engaged Dershowitz to sue Imus (successfully), was wondering earlier in the year about Dershowitz publicly speaking out conservatively on some issues, saying "he didn't need the grief" from the pc crowd at this point (semi-retired) in his life.
Dershowitz is back to his old publicity games defending Polanski.
Probably channeling F. Lee Bailey, imho.
