In a Austin, Texas city council meeting recently, discussions were taking place regarding security issues. One noteworthy element was the mention of the Municipal Court staff having to contend with sovereign citizens. In their memo, it was noted that:
“for decades there’s been frequent interaction with sovereign citizens at AMC, including disruptive and threatening behavior to members of the public and court staff.”
I am sure this is true for many other court personnel in the US and likely beyond.
