At the time, the officers were guarding the home of a police captain who was on Dorner's list of targets. They saw the pickup truck slowly driving through the neighborhood and opened fire, shooting one woman twice and injuring another female passenger.
The women were actually delivering newspapers in the neighborhood when an officer reportedly mistook the sound of a newspaper hitting a driveway as the sound of gunshot.
The women, who miraculously both survived the massive barrage of gunfire, were later awarded a $4.2-million settlement in a case against the city.
The prosecutor's office said it didn't believe the officers acted wrongly.
“The fear of Dorner was understandable and justified," the document said. "There is no evidence to suggest that the officers did not honestly believe that Dorner was in the vehicle, nor is there evidence to suggest that the officers did not honestly believe they were being fired upon."
LAPD police chief Charlie Beck had previously told the Times that he believed the officers violated department policy in the shooting, and also screwed up by shooting in each other's directions.
The attorney for the officers, meanwhile, blamed the mistake on LAPD leadership.
