From the ARMED CITIZEN AUGUST 2021 page of the NRA Official Journals:
On the evening of May 21, a 33-year-old man walked into a barber shop in Riverside, Calif., apparently intent on causing harm. According to the Riverside Police Department, the suspect, an ex-employee, started a fight with a former co-worker. During the fight, the suspect stabbed one of the male barbers, and, when a second employee tried to intervene, he was also stabbed. However, one of the victims was able to retrieve his firearm and shoot the attacker. The suspect was taken to the hospital, where he was pronounced dead by the coroner. The two stabbing victims’ injuries reportedly were not life-threatening and deputies said they considered the shooting to be a case of self-defense.
