In the Middle Ages the powers used a simple method to to tell who was lying or telling the truth, it was called trial by ordeal. Arkin is simply using a similar method. Arkins method: if the woman gets pregnant she was not raped, if she doesn't get pregnant, she was raped. It sure beats shoving one's arm into boiing water for a period of time, and if the arm doesn't heal right, the person was obviously telling a lie. They had a number of these tests and they sound pretty simple, and perhaps we are now see the wisdom of Arkin's methods. Sure the methods are from the past, but no one can label them progressive.
