I think Dershowitz is one of those "true believer" liberals, as opposed to the more radicalized Leftists who see everything as an expedient tool, an intermediate to be used in the pursuit of Marxist communism. I still strongly disagree with the Dershowitz liberals, but they at least are not thoroughly disingenuous like the radicals. And I have news for Dershowitz and his flavor of liberals -- the radicals on their end of the spectrum have lapped their asses. Look at how much more stridently left wing the Democrat Party is now, compared to a few decades ago. Dershowitz has also gotten a taste of the inherently anti-Jewish bigotry of the Left.
As for this case, Dershowitz seems to agree with what I postulated earlier, that this prosecutor has overcharged with the aim of reaching a plea agreement. She apparently believes this will (a) sate the bloodlust of the mobs, (b) give her political cover, and (c) give her notoriety as the prosecutor who stepped into the fray of a heated and complicated issue and saw to it that justice was done. Hopelessly naive.
And the idea that the judge should throw it out, what would happen if the judge did that? See the dichotomy the Left has established here? 1. Prosecute, convict, and sentence Zimmerman or 2. Bear the "responsibility" for what the mobs might do.
That's the state of jurisprudence now.
