What looked like the straightforward trial in Wichita, Kansas has been thrown into chaos by a judge's ruling. Scott Roeder confessed to shooting Dr. George Tiller to death in a crowded church last year. Tiller was known to perform late-term abortions. Last week, Judge Warren Wilbert said Roeder's defense could argue that he committed manslaughter, rather than first-degree murder because he believed he was saving the lives of innocent children.
