I think it goes without saying that those of us who are in the pro-life community would condemn the killing of anyone, that’s the whole point of our movement. We value human life because it’s been made in the image of God and it is not our place to end it.

One of the few doctors to provide late-term abortions in the United States has been gunned down in his Kansas church, and authorities said they have arrested a suspect in the case.
[…]
The gunman killed George Tiller just after 10:00 am (1500 GMT) in the lobby of Reformation Lutheran Church. Wichita officials said the 51-year-old man suspected of shooting Tiller was arrested some three hours later.
Long a lightning rod for anti-abortion activists, Tiller, 67, had already been picketed, bombed and shot in both arms.

And I think it goes without saying that a Christian is not called to murder anyone in the name of Christ. It is not our job to stop abortionists by deadly force, it is our job to spread the gospel of Jesus Christ. Anyone who uses violence in the name of Christ doesn’t understand what it means to be a Christian.
George Tiller wasn’t doing anything illegal and therefore didn’t deserve to die and he certainly didn’t deserve to die in a place where we worship our Lord. That a man calling himself a Christian would do that is so heinous that it defies description. I can’t even begin to fathom the thinking behind it. What would give him the right to think that Jesus would want him to enter a house of worship and gun down a defenseless man, who was serving the Lord on our day of worship, in cold blood is beyond me.
I know the pro-abortionists will say that this is the fault of the pro-life community but that would be a ludicrous assumption since we have continually condemned the violence against clinics and abortionist and do so again now. No one in our community could ever get the impression that we would support or condone such actions. The gun man is obviously deranged and doesn’t have a clear grasp of the Bible if he would commit such a heinous act, his actions prove it.
