Maybe into that “sovereign person” thing. Note that I use quotes. There are some Posse Commitatus types that claim this.
I used to run into these goobers on "survivalist" BBS. Oddly, a lot of them were from Pennsylvania.
Yeah, that was my first thought. I’m ashamed to say, but I was once employed in a seasonal position with the IRS (don’t judge; I was young and needed a job). Anyways, my job was processing and assigning written correspondence, and I got a lot of letters from tax protesters who would frequently use the term “sovereign person” while arguing about the 16th Amendment being illegal or whatever.
