But Roeder's violent right-wing extremism seems to extend beyond the issue of abortion. In April 1996, amid anxiety over the anniversary of the Oklahoma City bombing, Roeder was stopped by police after a motorist reported seeing a car with a license plate reading: "Sovereign -- Private Property -- Immunity Declared at Law --Non Commercial American."
("Sovereign citizens" claim to be unaccountable to the federal government, deriving certain rights under English common law. It's been a
favored legal strategy of various violent right-wing extremists, including white supremacists.)
When police searched Roeder's car, they found the makings of a bomb: a blasting cap; two six-volt lantern batteries, one wired with a clothespin and a cigarette wrapper; and a 1-pound can of black gunpowder. In Roeder's home, police found instructions titled "Underground Cookbook: Clothes Pin Time-Delayed Switch."
