LOS ANGELES (AP) — Video released from body cameras captures the chaos deputies encountered when they arrived at the scene of a mass shooting outside the Borderline Bar and Grill in 2018.

The video released Tuesday after a court fight by The Associated Press and other news outlets showed officers trying to find out what happened to one of their own as a gunshot victim lay bleeding in a parking lot and others ran to safety.

A dozen people, including a fallen sergeant, were killed after a gunman opened fire before taking his own life at the Borderline Bar and Grill in a Los Angeles suburb.
