Scott Philip Roeder was a Sovereign

[Unidyne]

This may be old news, but Scott Philip Roeder, the convicted murderer of Dr. George R. Tiller, was a follower of the sovereign citizen movement.

"However, Roeder's involvement with extreme causes was wider than simply anti-abortion extremists. He also had a long history of involvement with anti-government extremist movements such as the sovereign citizen and the tax protest movements. The sovereign citizen movement believes that a conspiracy took over the "real" government and the "false" government has no jurisdiction over them."
"In April 1996, Roeder was arrested in Topeka after deputies pulled him over for having a bogus sovereign citizen license plate on his vehicle and subsequently found bomb-making materials in his car. He was charged with criminal use of explosives and several traffic charges. The arrest came during the Montana Freeman standoff, a time when many in the sovereign citizen movement were expecting confrontations with the government."
Roeder was subsequently convicted of an explosives violation and sentenced to supervised probation. In 1997, a judge revoked Roeder's parole because Roeder refused to file an income tax return and other reasons. During the hearing, Roeder offered the standard tax protest argument that income taxes were voluntary."
"Roeder received a 16 month prison sentence. However, his conviction was subsequently overturned after a Kansas court ruled that police had obtained the evidence improperly and he was released in 1998."

The MSNBC Rachel Maddow Show managed to dredge up a video interview of Roeder from ca. 1995, in which he identified himself as a member of the Montana Freemen (and a believer in unlicensed driving):
