"A sincere and apparently well-grounded belief that a felony is about to be perpetrated will extenuate a homicide committed in prevention of it, though the defendant be but a private citizen" (25 Ala., 15.) See Wharton, above quoted, who embodies the doctrine in his text (Vol. 2, Sec. 1039).

Let us be grateful from our hearts that the old Mosaic law, "Whoso sheddeth man's blood by man shall his blood be shed," is shown by this memorable event to have not yet fallen altogether into innocuous desuetude; and let us give thanks to God that he has seen fit on this occasion to preserve from death at the hands of an intolerable ruffian the life of that high-minded, pure-handed, and excellent jurist and magistrate, Stephen J. Field.
The Philadelphia Times of August 15th has the following:
ONLY ONE OPINION.
Marshal Neagle Could Not Stand Idly By.
The killing of Judge Terry of California is a homicide that will occasion no regret wherever the story of his stormy and wicked life is known. At the same time, the circumstances that surrounded it will be deeply lamented. This violent man, more than once a murderer, met his death while in the act of assaulting Justice Field of the Supreme Court of the United States. Had he not been killed when he was, Judge Field would probably have been another of his victims. Terry had declared his purpose of killing the Justice, and this was their first meeting since his release from deserved imprisonment.
In regard to the act of United States Marshal Neagle, there can be only one opinion. He could not stand idly by and see a judge of the Suprene Court murdered before his eyes. The contumely that Terry sought to put upon the Judge was only the insult that was to go before premeditated murder. The case has no moral except the certainty that a violent life will end in a violent death.
