Another unpopular institution was that of Curfew Bell, introduced by the Conqueror ostensibly as a protection against fire, but in reality intended as a check upon the Saxons, to prevent them from meeting after dark, and discussing the shortcomings of their oppressors, or for other political purposes. The Anglo-Saxon Chronicle gives a pathetic account of the severity and injustice meted out by the Normans. "A.D. 1124. This same year after St Andrew's Mass, and before Christmas, held Ralph Basset and the King's thanes a 'géwitenemote' in Leicestershire, at Huncothoe, and there hanged more thieves than ever were known before, that is, in a little while, four and forty men altogether: and despoiled six men of their eyes and mutilated them. Many true men said that there were several who suffered very unjustly; but our Lord God Almighty, who seeth and knoweth every secret, seeth also that the wretched people are oppressed with all unrighteousness. First they are bereaved of their property and then they are slain. Full heavy year was this." And again, "then was corn dear, and cheese, and butter, for there was none in the land: wretched men starved with hunger: some lived on alms who had been erewhile rich: some fled the country, never was there more misery, and never heathen acted worse than these. The earth bare no corn, you might as well have tilled the sea, for the land was all ruined by such deeds."

If we may accept this as a true version of the condition of England and the English, it is abundantly clear that the system of police by decennary societies was inevitably doomed to failure after the Conquest. The two nations, who had little in common, who were in fact animated by bitter racial animosity, could not combine for any common purpose; and it is obvious that the "mutual security" plan can only be successful amongst a community bound together by the ties of family or friendship.

The sheriff's court never won the confidence of the people, and gradually certain neighbourhoods, or, more correctly speaking, certain lords more favoured than the rest, obtained the royal consent to the substitution of local police courts, under a steward nominated by the Lord of the Manor. These "courts of the leet" not only had the power to "inquire of and punish all things that may hurt or grieve the people in general, in their health, quiet, and welfare," but were authorised to abate or remove public nuisances.[23]

Courts Leet became so popular, and proved so successful, that we soon find them established, not merely in a few privileged places, but all over the country; before long the Sheriff's Tourn became the exception and the Court Leet the rule, the struggle for survival only coming to an end when the sheriff altogether ceased to trouble the village communities with his annual visit of inspection.

The rise of the Court Leet marks an important stage in the development of English police. The decennary system could only be of value as long as its strictly local character could be preserved, and the power of interference possessed by the Vicecomes was foreign to the national idea of police administration. Although the creation of the sheriff's court must only be considered as an ill-advised and novel attempt at centralisation, and its discontinuance a return to first principles, it was not to be expected that the Tourn, when once established, would be allowed to disappear until there was an alternative institution ready and able to take its place. On this account the appearance of the Court Leet was well timed, for the moment and indispensable for the future, to act as a link between ancient principles and modern practice.

When Henry II. returned from the Continent in 1170 he found it necessary to investigate the complaints that were persistently made against the sheriffs, who were said to have been guilty of oppression and extortion. The charges were well founded, and the result of his inquiry was that several were dismissed from their office, whilst a few years later the Assize of Northampton considerably reduced the authority of the remainder. In the years that follow we find evidence, over and over again, of the abuse of their power by the sheriffs, whose importance steadily declined in consequence; the decay of their office was gradual at first, but proceeded more rapidly, as we shall see, after the institution of "Conservators of the Peace" by Richard I. At the Council of Northampton provision was also made for holding assizes in the different counties of England. For this purpose the kingdom was divided into six circuits, and three judges, subsequently known under the title of "justices itinerant," were assigned to each circuit.

Notwithstanding the recent friction between the two nationalities (now happily on the wane), and all the evils which had accompanied it, hundreds and tythings continued to perform their executive functions as best they could, and not altogether without success; but the levying of amercements, which was essential to the system, was so liable to abuse at the hands of royal officers, and the fines grew so out of proportion to the offences for which they were exacted, that advantage was very properly taken of King John's humiliation in 1215 to insist that they should only be enforced in future "on oath being made by the worthy men of the district," and steps were taken to confine amercements to their proper limits. By Magna Carta police fines were henceforward to correspond in amount to the magnitude of the crime for which they were incurred, and might not be enforced except with beneficium competentiæ i.e. every man had a right to his bare living, the merchant to his merchandise, and the villein to his agricultural implements.[24]

In the following reign an attempt was made to put fresh life into the police administration that for more than a hundred years had been deteriorating; it was therefore ordained[25] that a view of frankpledge should be made every Michaelmas, and tything be kept as in the old days; the effort, however, was not a success, and before long the prestige of the institution was irrevocably damaged by the relief granted to the Baronage and Clergy by the Statute of Marlborough, which excused them from attendance at the Court, unless they received special orders to be present. In any case a return to the past was impossible, the country had outgrown the method of control that had once been efficacious, and altered conditions had completed the wreck of the decennary system that racial differences had commenced. From this time onwards, when frankpledge is spoken of, it must be understood to mean only the general principle that was the basis of the indigenous system; that is to say, a recognition of the bounden responsibility of every citizen to take his part in the duty of maintaining peace in the state; or, in other words, the liability that all men share to render police services when called upon to do so.
