If it could be conclusively proved or even rendered highly probable, that the capital punishment of an ox, which had gored a man to death, deterred other oxen from pushing with their horns, it would be the unquestionable right and imperative duty of our legislatures and tribunals to re-enact and execute the old Mosaic law on this subject. In like manner, if it can be satisfactorily shown that the hanging of an admittedly insane person, who has committed murder, prevents other insane persons from perpetrating the same crime, or tends to diminish the number of those who go insane in the same direction, it is clearly the duty of society to hang such persons, whatever may be the opinion of the alienist concerning their moral responsibility. Nor is this merely a hypothetical case or purely academical question. It is a well-established fact, that the partially insane, especially those affected with “moral insanity” or so-called “cranks,” have their intelligence intact, and are capable of exercising their reasoning powers freely and fully in laying their plans and in carrying out their designs. Indeed, criminals of this class are sometimes known to have entertained the thought that they would be acquitted on the ground of insanity, and have thereby been emboldened to do the deed; and it is by no means impossible, but highly probable, that a belief in the certainty of punishment would have acted as an effective deterrent. A case of this kind occurred in 1894 in England, where an inmate of a lunatic asylum deliberately murdered a lawyer, who was visiting the institution. The murderer declared that he had no grudge against his victim, but believed himself to be persecuted in general and wished to call attention to his wrongs by assassinating some official or prominent person. His method of redress was that of the ordinary anarchist; and his confession that he would not have dared to commit the act unless he had believed that as a certificated lunatic under confinement he ran no risk of being hanged, illustrates the point in question. There can be no doubt, for example, that the execution of Guiteau for the assassination of Garfield has greatly lessened the dangers of this kind to which the President of the United States is exposed; just as the swift and severe punishment of the Chicago anarchists has dampened the zeal and restrained the activity of the fanatics, who labour under the delusion that, in a free country, dynamite bombs are the fittest means of disseminating reformatory ideas and bringing about the social and political regeneration of the world.
