I used to work at Dominos in Tampa. Co-worker had just finished a delivery, was sitting in his car, windows down due to no AC. Suddenly a guy came up to the car yelling and screaming like he knew Cliff, the driver. Cliff, thinking it was a robbery reached in the center console of his car, got his gun, and shot the guy point blank in the chest. Cliff got out of the car, all wigged out, yelling at the guy, dying on the ground, when he saw a second perp on the other side of the car he shot again and hit that kid in the leg.
Cliff was subsequently let go by Dominos as it is against their policy for employees to have firearms during deliveries. Cliff was also unsuccessfully sued by the family of the dead criminal. Victims continue to be victimized even after the original incident.
