Meet the "pro-life" activist who shot and killed George Tiller. The suspected killer's right-wing extremism wasn't limited to anti-abortion-rights activism...

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."

...

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."

Creepiest detail:

When Roeder was arrested yesterday, he was driving a blue 1993 Ford Taurus. In the rear window of the car was a red rose—a symbol often used by anti-abortion activists—and on the back his car was a silver fish symbol with the word "Jesus" inside.

The part in the Sermon on the Mount about bomb making was always my favorite.
