First lamanaria are inserted into Momma's cervix. They swell with Momma's body fluids and dilate the birth canal. The trick is to dilate the canal just the right side. Not so small that the baby's hips and shoulders cannot be extracted from the womb. And not so large that the whole baby comes out. It's a bad day at the office for an abortionist when you've got a live baby. Your job is to produce a dead one.
After about 24 hours Momma comes back to the abortuary. The killer will reach into Momma's womb and try to remove baby feet first. If he is successful, he will pull baby out so that only her head remains in Momma. Then he will stab baby at the base of her skull. He then takes a suctioning tool and sucks baby's brains out. Success!
When abortionist Leroy Carhart sued the Bush Administration for signing a ban on such practices he said that not all such abortions are so clean. He said that frequently the baby cannot be positioned within the womb so easily. In those cases he reaches in with a grasping device (think pliers with sharp teeth) and grabs whatever is convenient. It might be a leg, hip or shoulder, whatever he can get. He then twists off the body part and pulls it out with whatever other tissue might still be attached. He does this to a live human being.
But the lawyers wanted to know about when the procedure works as prescribed by Haskell. When does the baby die? Carhart said he really didn't know. He likened the puncturing of the skull to a gun shot to the head. Not all gunshot victims die immediately. But surely the baby dies when her brains are sucked out. He still wasn't sure because sometimes the baby's heart continues to beat after her brains have been sucked out.
I suppose it's not uncommon for pro-choicers to make moral equivalents of killing human beings to killing dogs.
