concerned about ec

I've heard a lot of arguments against making Plan B, or emergency contraception, available over the counter. Coming to the situation already believing it should be available OTC so long as it meets the scientific safety standards for making a drug OTC, I find most of the arguments unpersuasive. But, today, I heard the strangest, and possibly weakest, argument yet. A woman who appeared on Nightline representing the "Concerned Women for America" said that she would worry about a 40-year-old man buying EC and giving it to a 14-year-old girl to cover up the fact that he is sexually abusing her. This confuses me. Obviously, an adult abusing a child and using a medication to cover his tracks is not something one would desire. But, is her argument then that it is preferable for the girl to become pregnant and either have a baby that is the product of rape and for whom she cannot care or have an abortion? Maybe I just don't get it. Or maybe the argument makes no real-world sense.
