The Lord Advocate was pleased to commend this witness, as having spoken out from a desire of doing justice and being of service to his country. Did his appearance this day indicate any such feelings? Do not the circumstances in which he brought forward this accusation show the baseness of his views? He has sworn that at first he did not accuse Mr. Brodie. No; it was not till his return from England that he took this course, when, finding that the sacrifice of mean victims was not leading to any steps being taken to procure him a pardon, and that the other unhappy prisoner at the bar had confessed his own guilt, but without accusing Mr. Brodie, he (Brown) gave the lie to his first declaration by criminating that gentleman; and the pardon, which has this day procured admission to his testimony, was obtained for him. The measures of the public prosecutor in this respect were highly proper, believing, as he no doubt did, the testimony of this man. But I leave it to you, gentlemen, to consider whether it is possible for any witness to stand in more suspicious circumstances; and whether, as several of the judges have told you, that had his conviction been in Scotland instead of England, they would have rejected his testimony, notwithstanding the pardon, you should not so lay aside his evidence altogether in justice to the prisoner, who ought not to suffer for a distinction which, however founded in law, is contrary to common sense or reason when applied to the credibility of the witness, of which you alone are the judges. I come now, gentlemen, to the direct proof of _alibi_. And here I readily confess that a proof of _alibi_ is generally resorted to only upon the most desperate occasions; and that such proof, when it is in contradiction to facts clearly substantiated by real evidence or parole testimony beyond all suspicion, must yield thereto. But, gentlemen, this is by no means the case here. The _alibi_ is established by the most direct and complete proof, in opposition to which nothing direct appears in evidence, unless the testimony of two witnesses, entitled to no credit from their characters, and swearing in circumstances the most suspicious. There are, indeed, other circumstances proved; with regard to which I am to address you afterwards. But these, if the depositions of Brown and Ainslie be laid aside, must appear to you so light when weighed against this evidence of _alibi_ that they must kick the beam. The _alibi_, gentlemen, is thus proved.
