WA Police seized more than 100 guns on the weekend in an operation authorities say was sparked by the shooting of two police officers in Victoria in August, allegedly by sovereign citizen Dezi Freeman.

But a radicalisation expert said the move may “enhance those very grievances of being targeted” felt by sovereign citizens, a group he says is “particularly attuned to being singled out”.

Professor Keiran Hardy said sovereign citizens posed a “unique challenge” due to their views on authority and the rule of law.
