In the United States city where Australian woman Justine Damond was killed, all police are required to wear body cameras. So why did the officer who shot her have his turned off? Minneapolis police shooting transcript: What happened on the night? The officers were responding to a 911 call by Ms Damond, who reported hearing a possible assault in an alley behind her home.

Questions have been raised about why there was no police footage of the incident, with all Minneapolis officers required to wear body cameras since the end of 2016. I have the same question everyone else has: ‘Why weren’t the body cameras activated? Minneapolis Mayor Betsy Hodges said. Justine Damond was apparently unarmed and in her pyjamas when the officer shot her. Did the officers break body cam policy? The Minneapolis Police policy and procedure manual says body cameras should be activated “as soon as possible, but before any citizen contact” and “prior to any use of force”.

Minneapolis police officer Mohamed Noor sits on a wall outside in plain clothes smiling into the camera. Officer Mohamed Noor and his partner’s body cameras were off. While the Minnesota Bureau of Criminal Apprehension is investigating the shooting, it will be the Minneapolis Police Department’s job to determine whether the officers violated its body camera policy. What we know about Australian Justine Damond, the police shooting that took her life and the officer who fired the fatal shot. This violation of policy thwarted the public’s right to know what happened to Ms Damond and why the police killed her,” ACLU-MN’s Teresa Nelson said. The two officers broke the policy, not only when they didn’t activate the body cameras before the incident, but also when they failed to do so after the use of force. Police officers must turn their body cameras on to record, but the Minneapolis Star Tribune reported they also “constantly record a 30-second video buffer, a so-called ‘lookback’ that allows officers to capture whatever happened in the half-minute before it’s activated”.

There has been no evidence that feature was used by the police officers either. Police car dashboard cameras can also be turned on manually, and are automatically activated when the vehicle’s lights and sirens are turned on. Could officers face consequences for not turning cams on? Ms Nelson called for consequences to be added to the policy “to ensure better compliance and accountability”. What are the rules for Australian police? Are police in Australia required to wear body cameras and if so, do they have to turn them on?

Triple J looks at the rules in each state and territory. But Radford University’s Professor Tod Burke said it may not be clear-cut why the body cameras were not activated and whether it constituted a breach of procedure. It depends if the cameras were attempted to be switched on and they just simply weren’t functioning,” Professor Burke told ABC News. So we don’t know the answer to that until the investigation takes place.

Professor Burke — a former Maryland police officer — said it could also be possible the officers “simply forgot”. What are the body camera rules for Australian police? Why did they kill her?
