The NSW opposition is calling for footage of an elderly grandmother being tasered by police to be publicly released, as the government says the issue is becoming politicised.
Clare Nowland, 95, was using a walking frame when she was tasered by police at Yallambee Lodge aged care facility in Cooma a week ago, after allegedly failing to drop a steak knife.
The dementia patient is now receiving end-of-life care after sustaining critical injuries.
Police Commissioner Karen Webb has been under pressure over her handling of the incident after saying she would not watch the video until all the evidence for the investigation was gathered.
Senior Liberal MP Damien Tudehope has called on the government to release vision captured on the two attending officers' body cameras, saying Mrs Nowland's treatment was of grave concern.
In a motion to parliament on Wednesday, he also called for regular updates on the progress of the investigation.
"It's not good enough for the police to come and say, 'I can take and release bodycam footage in circumstances where I go and make arrests all over the place',
"But when it doesn't suit them - it doesn't suit them.
"That's when the cover-up starts.
"This is especially pertinent when a member of the public is not a criminal or suspected criminal, but a frail elderly, vulnerable person with dementia."
The motion passed, however references to bodyworn vision were removed, making the result largely symbolic.
The government opposed the motion, with Treasurer Daniel Mookhey later saying "no one should be should be politicising what has proven to be very difficult circumstances for all involved."
Western NSW Minister Tara Moriarty said the investigation needed to run its course, promising the video would be released "at some appropriate point".
"There is no cover-up," she told parliament.
"The language used this morning by the opposition about a cover-up is also pretty despicable in this circumstance."
The motion was opposed by the Shooters, Fishers and Farmers and One Nation, with One Nation MP Rod Roberts calling it "voyeuristic".
The Greens supported the motion, saying police body-worn video was routinely released during the arrests of accused drug dealers or organised crime figures.
"We need to end police investigating police, right now," Greens MP Sue Higginson said.
"Calling for greater accountability is the only thing we have available to us."
Jeremy Buckingham from the Legalise Cannabis Party also supported the motion, adding he believed the family's consent was important.
""I can understand why (police) are reluctant to release this. It is obviously going to show police in a bad light."
The 33-year-old senior constable involved has been suspended on full pay and the investigation is being led by the homicide squad and the Professional Standards Committee of NSW Police, overseen by the independent Law Enforcement Conduct Commission.
