On your first appearance before the Court, do not waste your time and ours telling us so. We are likely to discover for ourselves that you are a novi… - Robert H. Jackson

The prosecutor has more control over life, liberty, and reputation than any other person in America. His discretion is tremendous. He can have citizens investigated and, if he is that kind of person, he can have this done to the tune of public statements and veiled or unveiled intimations. Or the prosecutor may choose a more subtle course and simply have a citizen's friends interviewed. The prosecutor can order arrests, present cases to the grand jury in secret session, and on the basis of his one-sided presentation of the facts, can cause the citizen to be indicted and held for trial. He may dismiss the case before trial, in which case the defense never has a chance to be heard. Or he may go on with a public trial. If he obtains a conviction, the prosecutor can still make recommendations as to sentence, as to whether the prisoner should get probation or a suspended sentence, and after he is put away, as to whether he is a fit subject for parole. While the prosecutor at his best is one of the most beneficent forces in our society, when he acts from malice or other base motives, he is one of the worst.

He who must search a haystack for a needle is likely to end up with the attitude that the needle is not worth the search.

Nothing better can come out of this meeting of law enforcement officers than a rededication to the spirit of fair play and decency that should animate the federal prosecutor. Your positions are of such independence and importance that while you are being diligent, strict, and vigorous in law enforcement you can also afford to be just. Although the government technically loses its case, it has really won if justice has been done.
