The prevalent idea, that a juror may, at the mere dictation of a legislature or a judge, and without the concurrence of his own conscience or understanding, declare a man "guilty," and thus in effect license the government to punish him; and that the legislature or the judge, and not himself, has in that case all the moral responsibility for the correctness of the principles on which the judgment was rendered, is one of the many gross impostures by which it could hardly have been supposed that any sane man could ever have been deluded, but which governments have nevertheless succeeded in inducing the people at large to receive and act upon. As a moral proposition, it is perfectly self-evident that, unless juries have all the legal rights that have been claimed for them in the preceding chapters, that is, the rights of judging what the law is, whether the law be a just one, what evidence is admissible, what weight the evidence is entitled to, whether an act were done with a criminal intent, and the right also to limit the sentence, free of all dictation from any quarter, they have no moral right to sit in the trial at all, and cannot do so without making themselves accomplices in any injustice that they may have reason to believe may result from their verdict. It is absurd to say that they have no moral responsibility for the use that may be made of their verdict by the government, when they have reason to suppose it will be used for purposes of injustice. It is, for instance, manifestly absurd to say that jurors have no moral responsibility for the enforcement of an unjust law, when they consent to render a verdict of guilty for the transgression of it; which verdict they know, or have good reason to believe, will be used by the government as a justification for inflicting a penalty. It is absurd, also, to say that jurors have no moral responsibility for a punishment indicted upon a man against law, when, at the dictation of a judge as to what the law is, they have consented to render a verdict against their own opinions of the law. It is absurd, too, to say that jurors have no moral responsibility for the conviction and punishment of an innocent man, when they consent to render a verdict against him on the strength of evidence, or laws of evidence, dictated to them by the court, if any evidence or laws of evidence have been excluded, which they (the jurors) think ought to have been admitted in his defence. It is absurd to say that jurors have no moral responsibility for rendering a verdict of "guilty" against a man, for an act which he did not know to be a crime, and in the commission of which, therefore, he could have had no criminal intent, in obedience to the instructions of courts that "ignorance of the law (that is, of crime) excuses no one."
