‘Sovereign citizen defence’ uses obsolete ancient law to challenge Covid regulations. They distribute fake legal documents to teachers, parents, and health workers outside schools and hospitals, accusing the Government of ‘vaccine genocide’. ‘Sovereign citizens' and ‘freemen on the land’ wrongly believe they possess legal power to bring politicians, civil servants and scientists before ‘common law courts’, claiming Covid restrictions and vaccinations are illegal. Now a newly-formed group, ‘Alpha Men Assemble’ (AMA), combines anti-vaccine and sovereign citizen beliefs. It trains members in ‘direct action’ in breaking through police lines, marching formations and sparring. They post training sessions online for UK members. Believing they are immune from government rules, they have violently confronted police in Australia and the US. UK’s AMA only started in December, but numbers swelled to 7,000 after a recent training session for recruits.
