Incorrect: a case is taken to trial when the evidence suggests a possibility of a crime. It is up to the grand jury NOT the prosecutor, to determine if a case should go to trial.
Of course, you and Derec are perfectly comfortable with prosecutors selectively applying the law as long as they aren't doing it to you.
That's not right. A prosecutor only takes a case to trial if he thinks he can win, i.e., prove guilt beyond a reasonable doubt. Prosecutors like to win; and they win often because they are selective of which cases go to trial, which ones plea, and which are just dismissed or not pursued. In any case, the prosecutor has an ethical responsibility not to prosecute a defendant based on a "possibility" that a crime occurred. Otherwise, the state bar may give him the Nifong treatment.
And FYI - not every state uses grand juries and in those that do the use varies.
He's mixing up taking it to trial with taking it to a grand jury.
