Of crimes injurious to the persons of private subjects, the most principal and important is the offense of taking away that life, which is the immedi… - William Blackstone

The English law is less embarrassed with inconsistent resolutions and doubtful questions, than any other known system of the same extent and the same duration. I may instance in the civil law: the text whereof, as collected by Justinian and his agents, is extremely voluminous and diffuse; but the idle comments, obscure glosses, and jarring interpretations grafted thereupon by the learned jurists, are literally without number. And these glosses, which are mere private opinions of scholastic doctors (and not, like our books of reports, judicial determinations of the court) are all of authority sufficient to be vouched and relied on; which must needs breed great distraction and confusion in their tribunals.

Of all the parts of a law the most effectual is the vindicatory. For it is but lost labor to say, “do this, or avoid that,” unless we also declare, “this shall be the consequence of your non-compliance.” We must therefore observe, that the main strength and force of a law consists in the penalty annexed to it. Herein is to be found the principal obligation of human laws. Legislators and their laws are said to compel and oblige; not that by any natural violence they so constrain a man, as to render it impossible for him to act otherwise than as they direct, which is the strict sense of obligation: but because, by declaring and exhibiting a penalty against offenders, they bring it to pass that no man can easily choose to transgress the law; since, by reason of the impending correction, compliance is in a high degree preferable to disobedience.

Of great importance to the public is the preservation of this personal liberty; for if once it were left in the power of any the highest magistrate to imprison arbitrarily whomever he or his officers thought proper, (as in France it is daily practised by the crown,) there would soon be an end of all other rights and immunities. Some have thought that unjust attacks, even upon life or property, at the arbitrary will of the magistrate, are less dangerous to the commonwealth than such as are made upon the personal liberty of the subject. To bereave a man of life, or by violence to confiscate his estate, without accusation or trial, would be so gross and notorious an act of despotism, as must at once convey the alarm of tyranny throughout the whole kingdom; but confinement of the person, by secretly hurrying him to jail, where his sufferings are unknown or forgotten, is a less public, a less striking, and therefore a more dangerous engine of arbitrary government.
