OOC: No sweat, took me a bit to figure that out.
The resolution protects children during and after birth. Not only would your suggestion (adding "prior to birth" in clause three) undermine the whole point of the resolution but it would also be incorrect, killing a child during birth is not an abortion.
IC: Well, we shall never agree on this, shall we? Killing a fetus during birth is the very definition of a partial-birth abortion.
