The very purpose of the First Amendment is to foreclose public authority from assuming a guardianship of the public mind through regulating the press… - 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.

The priceless heritage of our society is the unrestricted constitutional right of each member to think as he will. Thought control is a copyright of totalitarianism, and we have no claim to it. It is not the function of the government to keep the citizen from falling into error; it is the function of the citizen to keep the government from falling into error. We could justify any censorship only when the censors are better shielded against error than the censored.

It is Mr. Mellon's credo that $200,000,000 can do no wrong. Our offense consists in doubting it.
