What are you suggesting here? That by not outlawing abortions or jailing abortion providers, It’s the system’s fault that Roeder shot a man?
The abortions that Tiller specialized in were forbidden under Kansas law which provided that late term abortions were only legal when there was a "grave threat to the physical health of the mother."
Sebellius and others looked the other way and did not investigate or prosecute Tiller for his wanton disregard of Kansas law.
The fact of the matter is that if Sebellius and the Kansas authorities had done their job and shut down the clinic, George Tiller would be alive today (and rotting in prison). And there would be a lot of children alive today who might otherwise have been murdered by this animal.
So the answer to your question is... yes.
