Courvoisier v. Raymond

After chasing rioting would-be burglars out of his jewelry store and residence, Courvoisier (defendant) saw an unidentified man — actually police officer Raymond (plaintiff), responding to the commotion — approaching him with a hand near his hip pocket, and, not knowing Raymond was a police officer, shot him believing he was under further attack; the jury, instructed that it should find for Raymond if he wasn't actually attacking Courvoisier at the time of the shooting, found for Raymond.
