No and no, but we're not talking about criminal prosecution, rather whether a rape occured. In the absence of physical violence, there likely will be none. Paul doesn't specify a time frame, in many cases after a few days there will be no definitive evidence. Other than the perps confession. Of course we both know this isn't a serious proposal. And if it were, we'd simply take the victims word for it, which is essentially abortion on demand, for a certain time frame. Paul prefers not to acknowledge that.
I'm open to other explanation. In the absence of physical violence, how would you conclusively determine a rape was committed, other than the statements of the participants.
Lacking physical evidence (tears, abrasions, cuts and bruising) I would not support the rape exception.
