Nifong should be prosecuted and sent to the gallows. This kind of prosecutorial misconduct should be a capital offense.
The system has more or less taken care of Fong, but the system itself needs changing. The job of DA itself involves gigantic power and vanishingly close to nothing resembling accountability and, as such, it is a natural magnet to psychopaths like Fong. The job needs to be abolished and we need to get rid of the entire “adversarial” system of justice and adopt something like you see in France which they term an “inquisitorial” system in which the common incentive of all parties is to figure out what the **** happened and who if anybody needs to go to jail over it. NOBODY should ever have any sort of a career or money incentive to simply put people in prison.
