MINNEAPOLIS — The fatal shooting of an Australian woman by a Minneapolis police officer responding to her 911 call “should not have happened,” Police Chief Janee Harteau said Thursday, adding that the officer’s actions “go against who we are in the department.”

In her first public remarks since the death of Justine Damond, a 40-year-old life coach and bride-to-be, Harteau defended Officer Mohamed Noor’s training but criticized his actions.

“The actions in question go against who we are in the department, how we train and the expectations we have for our officers,” Harteau said. “These were the actions and judgment of one individual.”

She added: “This did not have to happen. Justine did not have to die.”

Damond had called 911 twice late Saturday to report a possible sexual assault in the alley behind her house on Minneapolis’ southwest side. Noor, who was in the passenger seat of a squad car, shot at Damond through the driver’s side window.

Noor has declined to speak with the state’s Bureau of Criminal Apprehension, which is handling the investigation. His partner, Matthew Harrity, told investigators he was startled by a loud sound right before Damond approached the police vehicle.

Neither officer had their body cameras turned on, which has drawn widespread criticism. Mayor Betsy Hodges said in a blog post Thursday that officers should turn them on any time they are responding to a call.

Harteau also said the cameras should have been on. She said the department is making changes to its policy on the cameras, rolled out citywide eight months ago, including looking at technology that would turn them on automatically.

Damond’s family has said they want changes in police protocols, including a look at how often officers are required to turn on their cameras. Their Minneapolis attorney, Bob Bennett, said they also “want to see this person not be an officer.”

“He shouldn’t be on the street with a gun making decisions,” Bennett said, adding that he wanted to see Noor’s training records, including how he did in situations involving when to shoot or not shoot.

Harteau said a report on Noor’s training showed no problems.

“This officer completed that training very well,” she said. “He was very suited to be on the street.”

Harteau faced several questions about her absence in the days following the shooting, which sparked anger and a demand for answers in the city and in Damond’s home country.

She said she had been backpacking in a remote area, it was “challenging” to return and that she had been in touch with her command staff.

The Damond family is just the latest to seek changes in police practices following a shooting.

Other police shootings around the U.S. — particularly the killings of black men by officers — led to calls for change that included everything from bias training for officers to upgraded technology. Sometimes those changes have been initiated by police departments. Other times they have been ordered by the federal government or through a lawsuit.

Minneapolis police said earlier this week they already were reviewing their body camera policy before Damond’s death. Issues being examined include having supervisors work with patrol officers to ensure the cameras are activated more frequently.
