"One other rule of law on this subject is necessary to be borne in mind--the substantive offence to which the advice or incitement applied must have been committed; and it is for that alone the adviser or procurer is legally accountable. Thus if one should counsel another to rescue one prisoner, and he should rescue another, unless by mistake; or if the incitement was to rescue a prisoner, and he commit a larceny, the inciter is not responsible. But it need not appear _that the precise time, or place, or means advised_, were used. Thus if one incite A. to murder B., but advise him to wait until B. shall be at a certain place at noon, and A. murders B. at a different place in the morning, the adviser is guilty. So if the incitement be to poison, and the murderer shoots, or stabs. So if the counsel be to beat another, and he is beaten to death, the adviser is a murderer; for having incited another to commit an unlawful act, he is responsible for all that ensues upon its execution. "These illustrations are drawn from cases of felonies, because they are the most common in the books and the most striking in themselves; but the principles on which they depend are equally applicable to cases of misdemeanor. In all such cases the real question is, whether the accused did procure, counsel, command, or abet the substantive offence committed. If he did, it is of no importance that his advice or directions were departed from in respect to the time, or place, or precise mode or means of committing it. "Gentlemen: The events which have recently occurred in this city, have rendered it my duty to call your attention to these rules of law, and to direct you to inquire whether in point of fact the offence of obstructing process of the United States has been committed; if it has, you will present for trial all such persons as have so participated therein as to be guilty of that offence. And you will allow me to say to you that if you or I were to begin to make discriminations between one law and another, and say this we will enforce and that we will not enforce, we should not only violate our oaths, but so far as in us lies, we should destroy the liberties of our country, which rest for their basis upon the great principle that our country is governed by laws, constitutionally enacted, and not by men. "In one part of our country the extradition of fugitives from labor is odious; in another, if we may judge from some transactions, the law concerning the extradition of fugitives from justice has been deemed not binding; in another still, the tariff laws of the United States were considered oppressive, and not fit to be enforced.
