"When you get given ammunition you don't want to give it away," he said. "Even when I said 'I was there, he said cuz' they argued with me. You can't change the minds of people who've already decided they don't like police."
The man was on the way to the gym when he spotted another man walking down Kamo Rd carrying a weed-eater around 9.30pm on Wednesday.
Thinking it was a situation that could get a few laughs online, he decided to take a short clip and later posted it on a private Facebook page with more than 17,000 followers.
Before he started filming officers had pulled over, left their vehicle, and asked the man trying to start his weed eater if he was alright, 'cuz', he said.
"The guy started pointing the weed eater at the police. It's a metre-and-a-half-long weapon – they could've got hurt," the man said. "It was a textbook takedown. The police were doing a good job that night."
Negativity aimed at police stemming from the video disappointed the man who posted it, as he says had no intention to fuel those attitudes.
"It was just for a laugh because there was a dude walking the road with a weed eater."
Police have been contacted for comment, but had not responded by edition time.
