"And first, all who are present and actually obstruct, resist, or oppose, are of course guilty. So are all who are present leagued in the common design, and so situated as to be able, in case of need, to afford assistance to those actually engaged, though they do not actually obstruct, resist, or oppose. If they are present for the purpose of affording assistance in obstructing, resisting, or opposing the officers, and are so situated as to be able in any event which may occur, actually to aid in the common design, though no overt act is done by them, they are still guilty under this law. The offence defined by this act is a misdemeanor; and it is rule of law that whatever participation, in case of felony, would render a person guilty, either as a principal in the second degree, or as an accessory before the fact, does, in a case of misdemeanor, render him guilty as a principal; in misdemeanors all are principals. And, therefore, in pursuance of the same rule, not only those who are present, but those who, though absent when the offence was committed, did procure, counsel, command, or abet others to commit the offence, are indictable as principal. "Such is the law, and it would seem that no just mind could doubt its propriety. If persons having influence over others use that influence to induce the commission of crime, while they themselves remain at a safe distance, that must be deemed a very imperfect system of law which allows them to escape with impunity. Such is not our law. It treats such advice as criminal, and subjects the giver of it to punishment according to the nature of the offence to which his pernicious counsel has led. If it be a case of felony, he is by the common law an accessory before the fact, and by the laws of the United States and of this State, is punishable to the same extent as the principal felon. If it be a case of misdemeanor, the adviser is himself a principal offender, and is to be indicted and punished as if he himself had done the criminal act. It may be important for you to know what, in point of law, amounts to such an advising or counselling another as will be sufficient to constitute this legal element in the offence. It is laid down by high authority, that though a mere tacit acquiescence, or words, which amount to a bare permission, will not be sufficient, yet such a procurement may be, either by direct means, as by hire, counsel, or command, or indirect, by evincing an express liking, approbation, or assent to another's criminal design. From the nature of the case, the law can prescribe only general rules on this subject. My instruction to you is, that language addressed to persons who immediately afterwards commit an offence,
