In 2009, the DHS released a rightwing extremists report which elicited a huge response negative response from Fox News and other conservative outlets.

CNN received the report. Get ready for another right wing freakout:

They're carrying out sporadic terror attacks on police, have threatened attacks on government buildings and reject government authority.

A new intelligence assessment, circulated by the Department of Homeland Security this month and reviewed by CNN, focuses on the domestic terror threat from right-wing sovereign citizen extremists and comes as the Obama administration holds a White House conference to focus efforts to fight violent extremism.

Some federal and local law enforcement groups view the domestic terror threat from sovereign citizen groups as equal to -- and in some cases greater than -- the threat from foreign Islamic terror groups, such as ISIS, that garner more public attention.​The Homeland Security report, produced in coordination with the FBI, counts 24 violent sovereign citizen-related attacks across the U.S. since 2010.

The government says these are extremists who believe that they can ignore laws and that their individual rights are under attack in routine daily instances such as a traffic stop or being required to obey a court order.

They've lashed out against authority in incidents such as one in 2012, in which a father and son were accused of engaging in a shootout with police in Louisiana, in a confrontation that began with an officer pulling them over for a traffic violation. Two officers were killed and several others wounded in the confrontation. The men were sovereign citizen extremists who claimed police had no authority over them.
