Over at Salon, they are saying
When his show airs tomorrow, Bill O'Reilly will most certainly decry the death of Kansas doctor George Tiller, who was killed Sunday while attending church services with his wife. Tiller, O'Reilly will say, was a man who was guilty of barbaric acts, but a civilized society does not resort to lawless murder, even against its worst members. And O'Reilly, we can assume, will genuinely mean this.
I'll go further than that. O'Reilly will use the killing as a way to attack his various enemies (mostly those he calls the "far left"). He'll say that this incident has nothing to do with remarks like those he's made over the years, and that any charges against him or similar conservative pundits are unfair. That the real victims are people like him. Etc.
UPDATE: I was right
