The title of the just-published Yale Law Journal Online essay "The Myth of Prosecutorial Accountability After Connick v. Thompson: Why Existing Professional Responsibility Measures Cannot Protect Against Prosecutorial Misconduct" says it all. Conclusion:
The data from our survey suggest four broad causes for the breakdown in attorney discipline systems with respect to prosecutors. First, the ethical rules that govern prosecutorial behavior fail to proscribe most forms of prosecutorial misconduct. Second, the procedures governing attorney discipline systems afford complainants too few rights and administrators too much discretion. Third, those who are in the best position to discover prosecutorial misconduct—judges, prosecutors, and defense attorneys—routinely fail to report it. Fourth, overlapping policing mechanisms create confusion about the appropriate locus of disciplinary authority.
