A POLICE officer's body camera footage of a man being shot dead by his colleague has been played during an inquest into the death of Anthony William Young.
The confronting images recorded at Coolum on the night of August 21 in 2013 were captured by Constable Jason Jupp on his personally-owned camera.
Const Jupp and partner Senior Constable Evan Condon were the first officers to arrive about 10.05pm at the Yandina Coolum Rd home of Young's brother David and his partner Louise Dekens.
Young had been staying with them after a relationship breakdown.
The officers were unaware the couple lay mortally wounded inside when they pulled up at the home.
Snr Const Condon was confronted by Young and shot him five times.
Young died in Nambour General Hospital about 1am the next day.
Queensland Police Service Ethical Standards Command officer Detective Inspector David Hickey was the first witness to be examined before Coroner Terry Ryan.
Det Insp Hickey had been charged with investigating the officers' actions.
He said the video footage gave an excellent indicator of the time the officers had to react to the situation.
"He was so close he actually brushed (Snr Const Condon) while he was falling," Det Insp Hickey said.
Counsel assisting the Coroner Stephen Keim questioned Det Insp Hickey about how he thought the officers had handled the situation.
Det Insp Hickey was satisfied they had acted appropriately, commending Const Jupp for going inside to secure the home and interviewing a neighbour who had given refuge to a young girl who witnessed the deaths of David Young and Louise Dekens.
He said officers trained to react to situations with muscle memory and instinct.
The rollout of police-issue body worn cameras, which began last week at the Gold Coast, was also discussed.
Det Insp Hickey said the devices were "not the be all and end all" but they were very helpful.
He also fielded questions about the revolving door treatment of mental health patients referred to by police officers when people with mental health concerns were released from hospital care very shortly after being taken there by police.
When asked if it led to repeat callouts, he said "yes, it is the same clients".
