Police officers being called to nursing homes is "more common" than the NSW police commissioner realises, an aged care expert says.
As the family of 95-year-old Clare Nowland maintains a bedside vigil, questions are being asked about why police were called to her nursing home at all.
Ms Nowland remains in a critical condition at Cooma Base Hospital after being tasered by a police officer, who was called to Yallambee Lodge residential aged care home on Wednesday because the great-grandmother was seen carrying a knife.
