What is a sovereign citizen?
A Sovereign citizen is someone that desires prison and ultimately death over a happy go lucky life. They basically want to do whatever the heck they want up to and including murder without any consequence.
If they hold this woman long enough to study her, I would bet she owes taxes, takes or sells drugs, and is probably wanted for other violations in other places. She will most likely get out tomorrow with a ticket for speeding and resisting arrest. That will enable her to put other citizens at risk so she can get more facial surgery and drugs. By accusing the UHP of stealing her car and blood, she is tacitly admitting that she has done worse than this before. Just for fun, the officer should recommend she get held for 3 days in the psycho ward and maybe she could get put away if she threatens someone. One way or another, her "sovereignty" will be taken from her at some point. The trick is not having someone else die because of her "freedom".
