Huh? Abortion center offered "free abortions" in memory of Tiller

Just sick:

An abortion business in Pennsylvania is drawing criticism for giving away free abortions on Tuesday in honor of slain late-term abortion practitioner George Tiller. The Philadelphia Women's Center said the free abortions were meant to show appreciation for Tiller, who was allegedly killed by extremist gunman Scott Roeder.

Town Hall columnist Jillian Bandes said a staff member at the abortion center said an unspecified number of free abortions were done yesterday for Tiller's “memory and legacy.”

However, by the end of the day, the center stopped doing free abortions and indicated it wouldn't likely do it again. (LifeNews)

I'm trying to grasp what sort of thinking could have led to the decision reported above. 

But I really lack the incentive, for some reason.
