Let's not beat around the bush here folks.
The man who (allegedly) killed Dr. Tiller was a member of an Operation Rescue cell. Operation Rescue helped him to stalk Dr. Tiller. And now Jill Stanek (you'll remember her from ads pushed by conservatives in the 2008 election) is working with Operation Rescue to publish the addresses and pictures of other doctors who perform abortions for their patients.
Lest you think this the fringe, Operation Rescue, Stanek, and other operatives appear quite regularly on the Fox News Channel.
