A video posted online captured a group of Los Angeles police officers in a confrontation with a man who they shot and killed on Sunday. Posted on Facebook, the video shows officers struggling with the man on a littered sidewalk before they open fire. Cmdr. Andrew Smith said the man “began fighting and physically resisting the officers” and that there was a struggle over one of the officers’ weapons. Two of the officers and a sergeant fired at the man, who was later pronounced dead at a hospital, Smith said. It was not immediately clear how many shots were fired but five gunshots in total are heard on the recording. The officers were responding to a robbery call, Smith added. Police also said a Taser was deployed during the altercation, but was deemed “ineffective.” Authorities have identified the man but it is unclear if he was homeless. Two of the officers involved were treated and released for injuries, according to Smith. Authorities are investigating the video to understand if the police officers warned the man before firing.
