But no one on that account has ventured to stigmatize the study of penal codes, and of the organisation for putting them into force, as ignoble or unprofitable. The sheriff, for instance, and his functions are approached with respect, by some historians even with awe. "Ah," say the despisers of military history, "but the sheriff is an instrument for compelling obedience to the law, not the leader of a host whose business it is to slaughter and destroy." The law! and what is the law but the formulated will which some section of the community, possibly a majority, but always in former days and frequently, even at present, a minority, seeks to impose upon the whole? And if breakers of the law resist the sheriff or policeman, will he not if necessary slaughter them, and destroy any shelter in which they may have taken refuge? Of course he will, and "the law" will uphold him for so doing. "But," reply the objectors, "you forget that civil law is not always a mere ordinance of man; it may have the sanction of divine authority." I speak here with all reverence, but how many are the armies and the leaders that have claimed that theirs was the cause of God, and have fared forth to war in His name? I am not speaking now of modern armies, though they too invariably invoke the help of the God of Battles, and call him to witness that their cause is just. Look at the Crusades on one side, look on the other at the mighty and overwhelming conquests of Islam. Look at the extinction of Christianity in North Africa; look at the eight centuries of conflict which banished the Mohammedan faith from Spain. Look at the religious wars of Christians in Europe; and not least at our own Puritans. Look finally at the bitter struggles of Hindu and Mohammedan in India. There was not one of these parties that did not claim, that did not for the most part heartily believe, that it was fighting to uphold the Law of God.

No! in its essence there is no difference between the force that imposes the will of a man upon his neighbour, and that which imposes his will upon his enemy. In the more primitive days of England the duties of the sheriff and his _posse comitatus_ extended to foreign enemies on English soil as well as to domestic law-breakers. Do we not to this day speak of those guilty of acts of violence as _breakers of the King's Peace_; men, that is, who seek to bring about a state of war and must be suppressed by the methods of war--taken prisoners, wounded or unwounded, and in the last resort killed? What was the origin of our own standing army? It was formed, as you doubtless know, out of a remnant of the victorious army of the Parliament which had overthrown the monarchy, a remnant which was saved from disbandment in order to overawe the turbulent of London, or in other words to serve as a body of police. It continued to be the only efficient instrument for imposing the will of the Government upon the people until 1829, when the present police-force was established. And the police are a standing army, neither more or less. The only essential difference between police and soldiers is that the former are employed mainly in the coercion of subjects of the State which levies them, while the function of the latter is to coerce the subjects of foreign states. It would not be inaccurate to say that police are soldiers against domestic enemies, and an army police against foreign enemies.
