Last Thursday morning, the Harris County Sheriff’s Office in Texas issued Cameron Brewer a body camera, making him one of the last deputies in the department to receive one. But two hours later, the camera was off and still charging in his patrol car when he came upon a fight at a Houston intersection.

Within 30 seconds of arriving, Deputy Brewer had exited his car, confronted a man in the street whose pants were around his ankles and fatally shot him once in the chest. While the deputy’s body camera did not capture the shooting, the Sheriff’s Office released footage from his car’s dashboard camera on Monday that offered another angle of the encounter, which many in Houston had quickly criticized as a case of excessive force and the latest example of an officer killing an unarmed black person.

In the video, Deputy Brewer, who is black, stops his car behind two men having an altercation, with shoving, in the street. The deputy can be heard yelling at Danny Ray Thomas, the man whose pants were down, as he walks toward the car. “Get down, man! Get on the ground,” the deputy screams repeatedly, before, out of the camera’s view, a single gunshot rings out. Mr. Thomas, 34, was pronounced dead at a hospital.
