They've caught the guy who shot and killed Dr. Tiller. According to KWCH-TV:

Deputy Chief Tom Stolz w/ Wichita Police Dept. says Dr. Tiller died of a single gunshot wound. The Associated Press says the man detained in the Kansas City area is 51-year-old Scott Roeder of Merriam, Kansas, according to Law Enforcement authorities in the area. Roeder has not been formally charged with the killing at this time. Police say he was arrested without incident after a traffic stop.

July 7, [1997], Kansas: Scott Roeder is sentenced to sixteen months in state prison for parole violations following a 1996 conviction for having bomb components in his car trunk. Roeder, a sovereign citizen and tax protester, violated his parole by not filing tax returns or providing his social security number to his employer.

He was also an active member of Operation Rescue; in 2007 a "Scott Roeder" posted this on the Operation Rescue website (which has been down throughout the day, probably more as a result of increased traffic than any sense of collective shame):

[May 19th, 2007 at 4:34 pm] Bleass everyone for attending and praying in May to bring justice to Tiller and the closing of his death camp. Sometime soon, would it be feasible to organize as many people as possible to attend Tillers church (inside, not just outside) to have much more of a presence and possibly ask questions of the Pastor, Deacons, Elders and members while there? Doesn’t seem like it would hurt anything but bring more attention to Tiller.

The Lawrence Journal-World and News relays that Kansas City station KMBC reported a post-it note with a phone number for Operation Rescue in his car at the time of his arrest.

He was a bombmaker, tax protester, member of the "sovereignity" movement, anti-abortion zealot and Operation Rescue member: the arrested suspect manages to fit every stereotype of right-wing militia teabagger.

Surprised?
