I'm going to be a clerk in a rural-ish suburban county this year, so I'm expecting to see a lot of it. The few that I've seen have mentioned the sheriff thing, but they get angry because they think only the county sheriff's office can bring charges against them. It only gets worse, because in my county, we have a county police force that shares jurisdiction with the sheriffs office, and the police are a state agency with county jurisdiction. The sovereign citizens go nuts over that distinction.

My main experience with it in the past has been with the Moorish Nation sovereign citizens, who don't do the whole middle-aged white guy sovcit thing with sheriffs. They're pretty interesting. They sue everybody in their fake courts and serve them with fake legal documents that purport to be default judgments. I worked for a PD who repped a guy whose family was all Moorish sovcits. They found out her name and address, and "sued" her, her husband, and a few other members of her family. They had fake process servers and everything. Letterhead and all.

I feel like state courts, especially on the East Coast, get it a little easier though. I couldn't imagine being a federal magistrate hearing cases in Nevada brought by the BLM against farmers and the like, they probably get crazy stuff daily.
