Much has been said, on this occasion, of the excitement which has existed, and still exists, and of the extraordinary measures taken to discover and punish the guilty. No doubt there has been, and is, much excitement, and strange indeed it would be had it been otherwise. Should not all the peaceable and well-disposed naturally feel concerned, and naturally exert themselves to bring to punishment the authors of this secret assassination? Was it a thing to be slept upon or forgotten? Did you, Gentlemen, sleep quite as quietly in your beds after this murder as before? Was it not a case for rewards, for meetings, for committees, for the united efforts of all the good, to find out a band of murderous conspirators, of midnight ruffians, and to bring them to the bar of justice and law? If this be excitement, is it an unnatural or an improper excitement? It seems to me, Gentlemen, that there are appearances of another feeling, of a very different nature and character; not very extensive, I would hope, but still there is too much evidence of its existence. Such is human nature, that some persons lose their abhorrence of crime in their admiration of its magnificent exhibitions. Ordinary vice is reprobated by them, but extraordinary guilt, exquisite wickedness, the high flights and poetry of crime, seize on the imagination, and lead them to forget the depths of the guilt, in admiration of the excellence of the performance, or the unequalled atrocity of the purpose. There are those in our day who have made great use of this infirmity of our nature, and by means of it done infinite injury to the cause of good morals. They have affected not only the taste, but I fear also the principles, of the young, the heedless, and the imaginative, by the exhibition of interesting and beautiful monsters. They render depravity attractive, sometimes by the polish of its manners, and sometimes by its very extravagance; and study to show off crime under all the advantages of cleverness and dexterity. Gentlemen, this is an extraordinary murder, but it is still a murder. We are not to lose ourselves in wonder at its origin, or in gazing on its cool and skilful execution. We are to detect and to punish it; and while we proceed with caution against the prisoner, and are to be sure that we do not visit on his head the offences of others, we are yet to consider that we are dealing with a case of most atrocious crime, which has not the slightest circumstance about it to soften its enormity. It is murder; deliberate, concerted, malicious murder. Although the interest of this case may have diminished by the repeated investigation of the facts; still, the additional labor which it imposes upon all concerned is not to be regretted, if it should result in removing all doubts of the guilt of the prisoner.
