The senator who sparked a furious debate on gun ownership this week once said he would be happy to let police "lie on the side of the road and bleed to death".
Video has emerged of Liberal-Democrat senator David Leyonhjelm speaking at a rally outside Queensland's Parliament in late 2013, where he complained about new laws potentially denying affiliates of outlaw motorcycle gangs their gun licences.
Senator Leyonhjelm was introduced to the rally as a senator-elect who had resigned from the Liberal Party "in disgust" over the Howard-era gun laws.
"The police and the public, at least the motorcycle riding public, are on a collision course and they wonder why no one comes to their aid when they are in trouble," he said at the rally.
"For myself, I am never going to help someone who thinks it's OK to pull me up, search me and threaten me with jail if I don't answer their questions, merely because I ride my motorcycle in company with a couple of other people.
"If that's what they think, they can lie on the side of the road and bleed to death."
The rally crowd, which had been enthusiastically cheering the speech, laughed nervously in response to the comment.
On Friday, a spokesman for the senator said he was a "libertarian who wishes no ill will on anyone, with the possible exception of authoritarians who would treat law abiding people like criminals".
"He is fed up by governments all over Australia that tell people who are doing no harm to others how to live their lives," the spokesman said.
Comment has been sought from the Queensland police union.
Senator Leyonhjelm ignited a civil war within the Liberal Party this week when he announced the government had been prepared to horse trade on gun laws to get its industrial relations legislation through the Senate.
He produced an email from August 2015 which outlined a deal between the senator and Justice Minister Michael Keenan and Immigration Minister Peter Dutton to end an import ban on the powerful Adler shotgun.
Former prime minister Tony Abbott denied any knowledge of a deal and tweeted his concerns, before doubling down in an interview with the ABC.
Mr Turnbull was forced to publicly contradict Mr Abbott's claims in Parliament and said he was "satisfied that the Minister for Justice acted in the full knowledge of the Prime Minister's Office at that time"
Last year, the Police Association of New South Wales called for Senator Leyonhjelm to be sacked from a law enforcement committee after he criticised police for their treatment of A-League fans at a Western Sydney Wanderers game.
"There is a saying amongst them that all cops are bastards," the senator said in November last year.
"The cops have earned that label, they have to un-earn it.
"The police are not our masters. They are our servants and I think they should remember that."
