Dumplin, The rapist dies only if he rapes a married or engaged woman. If he rapes a non-engaged virgin, he buys her as a sex slave. So maybe he already has several wives and the girl is only 12, yes she now becomes his next wive for the bargain price of a slave, 50 silver shekels. There is no provision for divorce, ever. Pretty sick, eh?
I recall that it's in the case of a married woman, they have to be found by another witness. In the case of engaged or non-engaged virgin, it is the "evidence of virginity" that is taken into account. Earlier in Deut 22:20,21 if there isn't "evidence of virginity" a girl will be stoned.
And remember if a woman is raped in the city but doesn't scream, she will also be stoned.
Maybe Angus could ask one of the WT geniuses to explain that.
