When a warrant is received by an Officer, he is bound to execute it, so far as the jurisdiction of the Magistrate and himself extends.—But the Constable having great original and inherent authority, may, without warrant, apprehend any person for a breach of the Peace: and in case of felony, actually committed, he may, on probable suspicion, arrest the felon: and for that purpose (as upon the warrant of a Magistrate,) he is authorised to break open doors, and even justified in killing the felon, if he cannot otherwise be taken.[106]

All persons present, when a felony is committed, are bound to arrest the felon, on pain of fine and imprisonment, if he escapes through negligence of the by-standers; who will (the same as a constable) in such case be justified in breaking open doors, to follow such felon, and even to kill him if he cannot be taken otherwise.[107]

The other species of arrest is called Hue-and-Cry, which is an alarm raised in the country upon any felony being committed. This was an ancient practice in use as far back as the reign of Edward the First, (1285) by which, in the then infant state of society, it became easy to discover criminal persons flying from justice.

However doubtful the utility of this ancient method of detecting offenders may be, in a great Metropolis, in the present extended state of Society, it is plain, that it has been considered as an important regulation of Police so late as the 8th George II. (1735;) since it was enacted in that year, (stat. 8, George II. cap. 16.) that the Constable who neglects making hue-and-cry, shall forfeit five pounds; and even the district is liable to be fined (according to the law of Alfred) if the felony be committed therein, and the felon escapes.[108] This, however, applies more particularly to the country, and where the practice cannot fail to be useful in a certain degree.

When a hue-and-cry is raised, every person, by command of the Constable, must pursue the felon, on pain of fine and imprisonment.

In this pursuit also, Constables may search suspected houses if the doors be open: but unless the felon is actually in the house, it will not be justifiable to use force; nor even then, except where admittance has been demanded and refused.

A Constable, even without any warrant, may break open a door for the purpose of apprehending a felon; but to justify this measure, he must not only shew that the felon was in the house, but also that access was denied after giving notice that he was a Constable, and demanding admittance in that capacity.[109] In the execution of the warrant of a Magistrate, the Officer is certainly authorized to break open the doors of the felon, or of the house of any person where he is concealed.—The first is lawful under all circumstances; but forcibly entering the house of a stranger may be considered as a trespass, if the felon should not be there.[110]

Such are the powers with which Constables are invested,—and which are, in many instances, enforced by penalties; that public justice may not be defeated.[111]

In addition to this, the wisdom of the Legislature, as an encouragement to officers and others to do their duty in apprehending and prosecuting offenders, has granted rewards in certain cases; Namely,
