THREE: An error, not less common than it is contrary to the object of societythat is, to the consciousness of personal securityis leaving a magistrate to be the arbitrary executor of the laws, free at his pleasure to imprison a citizen, to deprive a personal enemy of his liberty on frivolous pretexts, or to leave a friend unpunished in spite of the strongest proofs of his guilt. Imprisonment is a punishment which, unlike every other, must of necessity precede the declaration of guilt; but this distinctive character does not deprive it of the other essential of punishment, namely, that the law alone shall determine the cases under which it shall be merited. It is for the law, therefore, to point out the amount of evidence of a crime which shall justify the detention of the accused, and his subjection to examination and punishment. For such detention there may be sufficient proofs in common[133] report, in a mans flight, in a non-judicial confession, or in the confession of an accomplice; in a mans threats against or constant enmity with the person injured; in all the facts of the crime, and similar indications. But these proofs should be determined by the laws, not by the judges, whose decisions, when they are not particular applications of a general maxim in a public code, are always adverse to political liberty. The more that punishments are mitigated, that misery and hunger are banished from prisons, that pity and mercy are admitted within their iron doors, and are set above the inexorable and hardened ministers of justice, the slighter will be the evidences of guilt requisite for the legal detention of the suspected.[66]
