Soweit mir bekannt ist, werden die "sovereign citizens" in den USA als gefährlichste innerstaatliche Terroristengruppe eingestuft. Die englische Wikipedia listet eine ganze Reihe von Straftaten auf, darunter auch Morde an Polizisten. https://en.wikipedia.org/wiki/Sovereign_citizen_movement
- "In surveys conducted in 2014 and 2015, representatives of US law-enforcement ranked the risk of terrorism from the sovereign citizen movement higher than the risk from Islamic extremism. Sovereign citizens have also been identified as a potential terrorist threat by the New South Wales Police Force in Australia."
- "In May 2010, two police officers in West Memphis, Arkansas, were shot and killed by Joseph T. Kane after Kane and his father were the subject of a traffic stop. Kane and his father were later identified as members of the sovereign citizen movement."
- "On June 20, 2012, Anson Chi was arrested by federal authorities for allegedly trying to blow up a natural gas pipe line in a residential area of Plano, Texas."
- "On August 16, 2012, two sheriff's deputies were shot to death and two others seriously wounded after having been ambushed near LaPlace, Louisiana. Authorities arrested seven suspects, two of whom have been identified by law enforcement as members of a sovereign citizen's group."
