Is prosecutors were always right, we wouldn't need trials. We have an advocacy system. The prosecutor is not fighting for the truth, he is presenting one side only.
snedden botched this.
The job of the prosecutor is NOT just advocacy. It is to labor for truth. The prosecutor has just as much duty to see the weaknesses and NOT prosecuting a bad case as prosecuting the good cases.
Otherwise the prosecutor's job is to win at any cost. (a mistaken notion of many a prosecutorial hack)
