Then, Gentlemen, the general question occurs, Is it satisfactorily proved, by all these facts and circumstances, that the defendant was in and about Brown Street on the night of the murder? Considering that the murder was effected by a conspiracy; considering that he was one of the four conspirators; considering that two of the conspirators have accounted for themselves on the night of the murder, and were not in Brown Street; considering that the prisoner does not account for himself, nor show where he was; considering that Richard Crowninshield, the other conspirator and the perpetrator, is not accounted for, nor shown to be elsewhere; considering that it is now past all doubt that two persons were seen lurking in and about Brown Street at different times, avoiding observation, and exciting so much suspicion that the neighbors actually watched them; considering that, if these persons thus lurking in Brown Street at that hour were not the murderers, it remains to this day wholly unknown who they were or what their business was; considering the testimony of Miss Jaqueth, and that the club was afterwards found near this place; considering, finally, that Webster and Southwick saw these persons, and then took one of them for the defendant, and that Southwick then told his wife so, and that Bray and Mirick examined them closely, and now swear to their belief that the prisoner was one of them;—it is for you to say, putting these considerations together, whether you believe the prisoner was actually in Brown Street at the time of the murder.
By the counsel for the prisoner, much stress has been laid upon the question, whether Brown Street was a place in which aid could be given, a place in which actual assistance could be rendered in this transaction. This must be mainly decided by their own opinion who selected the place; by what they thought at the time, according to their plan of operation.
If it was agreed that the prisoner should be there to assist, it is enough. If they thought the place proper for their purpose, according to their plan, it is sufficient. Suppose we could prove expressly that they agreed that Frank should be there, and he was there, and you should think it not a well-chosen place for aiding and abetting, must he be acquitted? No! It is not what I think or you think of the appropriateness of the place; it is what they thought at the time. If the prisoner was in Brown Street by appointment and agreement with the perpetrator, for the purpose of giving assistance if assistance should be needed, it may safely be presumed that the place was suited to such assistance as it was supposed by the parties might chance to become requisite.
