The officer was dismissed for violating the Baton Rouge police department's standard on use of force and for losing his temper in the 2016 shooting of Alton Sterling that inflamed racial tensions.
A white Louisiana police officer was fired on Friday and a second suspended for the killing of Alton Sterling, a black man shot in a 2016 incident that inflamed the US debate on racial bias in law enforcement, a police official said.
Baton Rouge officer Blane Salamoni, who shot Sterling in a confrontation outside a convenience store, was dismissed for violating department standards on use of force and for losing his temper, Police Chief Murphy Paul told a news conference.
The second officer, Howie Lake, was suspended for three days for failing to maintain his composure. The decisions followed an administrative review of the July 2016 shooting, and both officers plan to appeal, Paul said.
The steps are designed "to bring closure to a cloud that has been over our community for far too long," he said.
Sterling was among black men slain by police whose deaths sparked U.S. protests and helped fuel the Black Lives Matter movement.
Police released four videos of the confrontation with Sterling outside a convenience store, where he was selling CDs.
Paul called the footage from a police dash camera, officers' body cameras, and a store surveillance camera "graphic and shocking to the conscience."
Yelling with expletives
Salamoni's camera shows him yelling at Sterling with expletives to put his hands on a car. He points a gun at his Sterling's head and shouts he will shoot him if he moves.
While struggling with Sterling, both officers' cameras came loose. Lake's footage ends by showingSterling on his back in the parking lot, blood draining from his body.
Sterling, 37, was shot after a resident reported he had been threatened by a black man selling CDs. Police said Sterling was trying to pull a loaded gun out of his pocket when Salamoni opened fire.
Lawyers representing Sterling's five children applauded Salamoni's firing, but expressed disappointment that the officers would not face charges.
"The person who was out of control was Blane Salamoni," attorney Michael Adams said at a news conference. "The person who stood by and let him be out of control was Howie Lake. That’s a tragedy."
Louisiana Attorney General Jeff Landry said this week that Lake and Salamoni would not face charges since they had reason to believe that Sterling was armed and was resisting arrest.
The US Department of Justice declined to prosecute the officers for civil rights violations in 2017, citing insufficient evidence.
