Kane, who posted Internet comments questioning federal and local governments' authority, had recently complained about being busted at what he called a "Nazi checkpoint" near Carrizozo, N.M. Court records there showed he spent three days in jail before posting a $1,500 bond on charges of driving without a license and concealing his identity, according to published reports.
Mark Potok, of the Southern Poverty Law Center in Montgomery, Ala., said some anti-government extremists "would simply very much like to believe that they really don't owe taxes."
"They don't believe that they are subject to most criminal laws, and they definitely don't believe that they can be required by the government to do such things as get drivers' licenses or register their cars," Potok said.
Suarez, who lives in Springfield, Ohio, said he first met Kane in 2004 but lost contact with him several years later. Though Kane was offering advice on eliminating debt, his methods concentrated on overcoming administrative obstacles and not on any overt anti-government resistance.
"The guy was very much under control all of the time," Suarez told ABCNews.com. "I never remember him raising his voice."
Suarez said Kane seemed to change after the death of his first wife Hope of an apparent heart attack a couple years ago.
"I think his governor was removed," Suarez said. "Hope did a lot to dial back Jerry, to keep him under control, and when she died anything that was peripheral to him to put the brake on was gone," Suarez said.
The confrontation between the police and the Kanes was the latest evidence of growing violence by those who distrust the government.
In February, a Texas man who was being dunned by the IRS for back taxes crashed a plane into a office complex that housed IRS office, killing one employee.
In March, a shooting outside the Pentagon injured two officers. Also in March, nine members of a self-styled militia group called Hutaree were arrested in a raid and charged with planning an ambush of police officers.
