Australian sovereign citizen faced court more than 200 times
John Wilson has been identified by senior police sources as an extremist member of the sovereign citizen movement in Australia.
The 73-year-old retired dentist has been fighting the system for 20 years.
His path towards sovereign ideology started in the late 1990s, when he was evicted from his home because he refused to acknowledge the mortgage over his house.
"It means you are your own master, in other words you have the right to your own body, your own freedoms, and if anybody wants to impose something upon you, they have to do it lawfully.
"If you are a sovereign person, you make the laws for yourself. You decide in your own conscience what you want to do."
Mr Wilson only pays fines or taxes when he thinks they are fair. He has been to court more than 200 times and jailed.
In 1997 he threw a plastic bag containing yellow liquid at a Supreme Court judge, in 2006 he attempted a citizen's arrest of a Supreme Court judge and in 2009, Mr Wilson sent a letter to the police commissioner.
In it, he threatened to burn down the premises he was evicted from.
He said that he was the victim of a government conspiracy and that there were hundreds of other Australians who shared his beliefs.
"There would be many hundreds scattered across the continent. The Queenslanders are very conscientious, the Victorians are doing a good job and even now in Western Australia we are getting more and more farmers and ordinary people, saying no, this is not right," Mr Wilson said.
"At the moment I have membership of about 95 people, but I haven't really pushed it."
Deadly US attacks linked to movement
The sovereign citizen movement began in 1969 in the United States as an anti-tax, anti-government group called Posse Comitatus.
Members believed that the United States federal authority was unlawful, and only accepted small levels of government.
Up to 300,000 Americans identify as sovereign citizens, according to the Southern Poverty Law Centre. Of those, 100,000 are considered extreme.
Before the 2001 World Trade Centre terrorist attacks in New York, the most destructive loss of life during peacetime in the United States was the Oklahoma City bombing in 1995.
168 people died, including 19 children under the age of six.
The two key conspirators were domestic terrorists and Timothy McVeigh's partner in the attack was Terry Nichols, a person designated by the FBI as a sovereign citizen.
Since the Oklahoma bombing, 32 law enforcement officers have been murdered by domestic anti-government extremists in America.
Two of the officers killed were serving under former Chief of the West Memphis police, Bob Paudert in May 2010. One of them was his son, Brandon Paudert.
"It has been five-and-a-half years since he has been killed and it was the most devastating event that has occurred in my life," Bob Paudert told 7.30.
Sergeant Brandon Paudert and his partner, Officer Bill Evans, were shot and killed during a traffic stop by sovereign citizen Jerry Kane Jr and his 16-year-old son Joseph Kane.
"Brandon and Bill were killed because they had never heard of sovereign citizens. It was something new to them, they didn't know about them," Mr Paudert said.
"I am convinced of this — if they knew and they had the training that we are now giving officers around the country and around the world, they would be alive today. They would be with us."
Since their deaths, Bob Paudert has worked closely with the Southern Poverty Law Centre in Alabama and the FBI to train law enforcement officials in the United States and Canada about the dangers sovereign citizens potentially pose.
"No-one had heard of sovereign citizens in May 2010, now the FBI says that they are the number one threat in this country. Australia is facing a similar scenario that we went through and it's starting the same way," he warned.
"They didn't commit acts of terrorism over here at one time. Now they do. And you can't wait. You can't wait until you lose officers, or officers are killed, to decide to do anything."
Number one terrorist threat on the FBI's watch list.
