There are two powerful, sobering elements to the slaying of the doctor who performed late-term abortions in Kansas.
The first is that he was gunned down in his church, shortly after the service had begun, in front of his wife.
The second is that it happened on Pentecost.
Pro-lifers have rushed to condemn the murder, and to voice understandable fears that it will be used to tar the pro-life movement as extremist.
But how will Christians face the probability that, when the killer is apprehended, he will turn out to be a Bible believer claiming to have a divine mandate -- as so often before? The last murder of an abortionist, the 1998 killing by James Kopp of Dr Slepian, was carried out by a Lutheran turned Traditionalist Catholic.
What Dr Tiller did was appalling. But he had his humanitarian reasons for doing it. He was a churchgoing family man.
The hostility and violence directed at Dr Tiller made him even more determined to carry on doing what he did. He was showered with pro-choice awards and is now, in death, a pro-choice martyr.
The violent fury directed against him led to more late-term abortions and culminated in a murder.

That question was asked over Notre Dame. It is being asked with more urgent force tonight.
