The FBI considers sovereign citizens an anti-government extremist movement.
Sovereign citizens believe the U.S. government is illegitimate and actually a corporation that secretly sold bonds using citizens as collateral. There are variations, but followers generally believe the people are creditors who have a right to collect from the government and don’t have to follow its laws.
Sovereign citizen ideology, tinged with antisemitism, teaches that a shadowy group secretly took over the U.S. government during the 19th century and has been using financial contracts to enslave Americans. Some followers have resorted to violence – even the murder of law enforcement officers. That is rare, although adherents are known to escalate police traffic stops, sometimes ending in scuffles and arrest.
