^^Not just locked up...but also 'fixed' so they can't have any more children...sorry but when you are that screwed up you forfeit your rights in my opinion.
Hammurabi's Law would sort this whole sordid business out easily without ever leaving a chance for a repeat offense down the road.
I think anyone who would consent to have their child raped deserves the same penalty as the offender. No real purely good human being let alone a parent would ever subject a child to such a disgusting act.
