While walking home one evening, Harold, an off-duty police officer, was accosted by Jones, a stranger. Jones had been drinking and mistakenly thought Harold was a man who was having an affair with his wife. Intending to frighten Harold but not to harm him, Jones pulled out a knife, screamed obscenities, and told Harold he was going to kill him. Frightened and reasonably believing Jones was going to kill him and that using deadly force was his only salvation, Harold took out his service revolver and shot and killed Jones. Harold is charged with murder. Harold's claim of self-defense should be 
sustained, because Harold reasonably believed Jones was planning to kill him and that deadly force was required.  sustained, because the killing was in hot blood upon sufficient provocation.  denied, because Jones did not in fact intend to harm Harold and Harold was incorrect in believing that he did.  denied, because Harold was not defending his home and had an obligation to retreat or to repel with less than deadly force.
