oompa, I'm not totally convinced that Deuteronomy 22:28-29 refers to a rape. I think it is speaking of a consentual encounter. See this explanation of the Hebrew words used from the Blue Letter Bible: http://www.blueletterbible.org/Bible.cfm?b=Deu&c=22&v=1&t=NASB#conc/28.
Keep in mind too, that societies views about virginity were very different during Biblical times than they are in western culture today.
