Prosecutor Misconduct, wrongful conviction and accountability

Many of the wrongful convictions in this country are caused by, or could have been prevented,  if prosecutors' took their obligations more seriously.  Under due process, the Supreme Court has said  thatthe ultimate duty of a prosecutor is to see that "justice is done."  However, few prosecutors are ever held accountable by the voters or by the courts.  This case from Texas is, hopefully the beginning of a trend.
