I’ve made my thoughts clear on the unraveling of the DSK case, but one aspect that should pointed out: The integrity with which Cy Vance’s office acted when they found information that could torpedo their main witness’s credibility. Reporters are calling this a “black eye” for Vance, but in fact he played by the rules on this one and did the stand-up thing. Prosecutor’s offices around the country have (unlawfully) withheld exculpatory evidence, sending innocent people to jail and even death row just to avoid embarrassment. High-profile cases like this one can encourage prosecutors to save their own skin and prop up their case at all costs (see, e.g., Mike Nifong). There are many ways I wish the DA’s office had better handled the current situation, but properly turning over this information to the defense isn’t one of them.
