(711) justitia non debet claudicare; et celeris, quia dilatio est quædam negatio (2 Inst. 56): Justice ought to be unbought, because nothing is more hateful than venal justice; full, for justice ought not to halt. and quick, for delay is a kind of denial. where an officer or his assistant, in the due execution of his office, arrests, or attempts to arrest, a person for felony, or a dangerous wound given, and he having notice thereof flies, and is killed by such officer or assistant in pursuit; (5) where, upon such offence as last described, a private person, in whose sight it has been committed, arrests, or endeavors to arrest, the offender, and kills him in resistance, Justitia est virtus excellens et or flight, under similar circumstances. Altissimo complacens (4 Inst. 58): JusJustitia est duplex: viz., severe puniens et vere præveniens (3 Inst. Epil.): Justice is double; punishing severely, and truly preventing. 3. Where committed for the preventice is excellent virtue and pleasing to the Most tion of any forcible or atrocious crime, but High. not if the crime is unaccompanied by force. 24. When two persons, being shipwrecked, get on the same plank, but finding it not able to save them both, one of them thrusts the other from it, whereby he is drowned. This is justifiable upon the great universal principle of self preservation. 4 Steph. Com. (7 edit.) 48. See HOMICIDE, § 4.
