The Police Association of NSW is furious at the comments, labelling them ill-informed.

"The senator, by repeating those comments and backing them up is not acting how any elected official should behave. Such attitudes and vitriol are, and always will be, an affront to community decency and values," PANSW president Scott Walker said.

"Fringe dwellers should have no platform to promote and extend their extremist views, especially at a time when police officers are themselves under the most serious threat levels in our history."
