Wow. That is pretty amazing. The paranoid side of me says " Oh no, what does Dershowitz know that we don't know?"
I wouldn't get too paranoid. I have a habit of watching cable news when I'm at home practicing my trumpet in the afternoon and I've seen that type of statement out of Dershowitz before (not that it doesn't surprise me every time). Even though his personal politics don't really line up with anyone in Freeperland, has does seem to have a very deep respect for the American judicial system. I can't really cite anything specific-you're just gonna have to take my word for it.
Not that that makes him any less of a tool. Har Har.
