Considering that it was clearly intended to terrorize doctors to stop performing legal abortions, I would say yes.
CNN reports:
George Tiller, whose Kansas women’s clinic was the epicenter of the state’s battles over abortion for nearly two decades, was shot and killed at his church Sunday morning, his family said.
Tiller, 67, was one of the few U.S. physicians who still performed late-term abortions. He survived a 1993 shooting outside his Wichita clinic.
He was fatally shot shortly after 10 a.m. Sunday at Reformation Lutheran Church, Wichita police said.
Sunday afternoon, authorities took a man into custody near Kansas City after stopping a car that matched a description of the killer’s getaway vehicle, according to sheriff’s deputies in Johnson County, Kansas. No charges had been filed.

On its Web site, [the extreme anti-abortion group] Operation Rescue refers to Tiller as a “monster” who has “been able to get away with murder.” And Operation Rescue founder Randall Terry, who is no longer affiliated with the group, called Tiller “a mass murderer.”“We grieve for him that he did not have time to properly prepare his soul to face God,” Terry said in a written statement. “I am more concerned that the Obama administration will use Tiller’s killing to intimidate pro-lifers into surrendering our most effective rhetoric and actions. Abortion is still murder, and we still must call abortion by its proper name.”
The 1993 attack on Tiller left him wounded through both arms. An ardent foe of abortion, Shelley Shannon, was convicted of attempted murder and is serving a 20-year sentence in federal prison for the shooting.
If Tiller was slain because of his work, he would be the fourth U.S. physician killed by abortion opponents since 1993. In addition, a nurse at a Birmingham, Alabama, clinic was maimed and an off-duty police officer was killed in a 1998 bombing by Eric Rudolph, who included abortion among his list of anti-government grievances.
