The year after Tonn started working in Vallejo, he chased an unarmed man who was driving a stolen car. The man crashed into someone’s front yard, then reversed into Tonn’s car. Tonn doesn’t remember feeling the impact, but in two seconds he shot eighteen rounds from his Glock into the car, injuring the man.
The officer who wrote the police review of the shooting was Kent Tribble, who once, when responding to a domestic dispute, went to the house of a Black man by mistake, Tased him through his bedroom window after the man shouted profanities at him, and later charged him with resisting arrest. On another occasion, when he was off duty, he pulled a gun on two men in Bend, Oregon, during a drunken confrontation after leaving a bar. (Tribble did not respond to a request for comment.) A couple of years later, Tribble was promoted to lieutenant. When he reviewed Tonn’s shooting, he wrote that Tonn had acted in accordance with his training.
