I think this is too myopic a view. Whether or not one is a party in a court proceeding doesn't mean you don't have "your day in court," which is just a chance for you to share your account of what happened. That account may be an oral recantation or DNA you provide as part of the investigation. In either case, the important part is that you, by offering evidence and testimony, are doing a service to society by helping remove a rapist from the streets, thus making society safer. Why the government thinks its a good idea to reward this service with later invasions of privacy is beyond me.
