This DUmmie's whole line of thinking is just Bullshit.
One guy whose specialty and pride is to perform late-term abortions which virtually no one else would perform is murdered by a disturbed fanatic, and this is enough to intimidate a whole profession into refusing to do abortions? BULLSHIT!!!
What is almost certainly happening is that with the advent of newer and better ways to see the actual living fetus as it develops in real time, more and more practioners are finding it impossible to deny the humanity of that "inconvenient little clump of cells".
(Saying this as I look at the ultrasounds of my 20 week first grandson, and shudder at the thought of people who would rip him from my daughter-in-law's womb without a second thought. Monsters.)
