Judge Kenneth Johnston KC said they acted in genuine fear for the safety of the woman, the child and themselves.
A man who saw what happened, and who wished not to named, said he was at home that day when he heard a child and could not tell whether they were crying or laughing.
“Then I heard a male voice in a different tone, and it ... didn’t sit well with me, and I thought, that doesn’t sound right.”
When he went outside and saw the man had a weapon, he called the police.
“It was clear that he was violent and not rational,” he said.
“He was basically waving that around belligerently, kind of seemingly at nothing, but also in a threatening manner ... deliberately hacking away at the bus stop whilst the woman and child were inside that bus shelter, I guess trying to stay as far away from him as they possibly could.”
Once the man was tasered, he hit the ground hard, the witness said.
“I distinctly remember the sound of him hitting the road, [I’ll] never forget that.
“It was basically just a large slap.”
He was impressed with officers’ actions, saying it was, at maximum, one minute between their arrival and disarming the man.
“I thought their response was fantastic ... they’re doing what they’re there to do, which is to protect the community, and they did it swiftly.”
If they had not, the situation could have been a lot worse, he said.
“It was an appropriate response, given that there was ... at least the way it appeared to me, a life-threatening situation.”
The IPCA report said the child was uninjured and the woman suffered a deep cut to her thumb after pushing the man’s weapon away from her.
