What's the difference, really?

The strange legal dichotomy: if the baby is still in its mother when it is killed, it is abortion and it's perfectly okay in the eyes of the law. But if the baby makes it out of the womb alive, then killing it becomes murder. Here is an example of that strangeness, and also proof that abortionists are callous baby-killers and not really humanitarians with a tender concern for women's health and well-being (but we already know that, don't we?).
