A Biblical Response, like you mention, would land the rape victim in Jail for life...;-(
Only if convicted: Shoot, shovel, and shut up. Alternatively, come back an hour or a day later, stab the rapist to death (but stop after the first lethal blow) and report both the recent rape and a second attempted rape, with the attempt stopped because the victim was armed the second time. Tell the cops it was self defense, point out evidence of the recent rape, and don't provide any more details. Get a good lawyer and tell him, "I didn't report the rape because I was embarrassed, and couldn't prove it wasn't consensual, but I carried a knife just so I could stop the attack if the predator came after me again. I didn't want him dead, I just wanted the attack to stop." A good lawyer can work with that. Even with the risk of conviction, it's worth stabbing/shooting those perverts if it makes rape too risky a crime to attempt.
