“Under United States Supreme Court precedent, it is relatively easy to sue police officers who commit misconduct, but federal law still provides enormous protections to prosecutors. Individual lawyers in district attorneys’ offices enjoy complete immunity from being sued if they make mistakes in the courtroom — even those that lead to wrongful convictions. The unjustly imprisoned in New York are also barred from suing the state unless they can prove conclusively that they are innocent, not just the victims of an unfair trial.”
