Police in Western Australia have seized guns and revoked or suspended firearms permits from dozens of owners linked to what investigators describe as sovereign citizen ideologies, or views that reject government authority.
The crackdown on firearm users follows the fatal shooting of two police officers in Victoria in August. The suspect in those killings, 56-year-old Dezi Freeman, remains at large, weeks after he is said to have killed two officers visiting his rural property to serve a search warrant.
