A second and third rape allegation provides a lot of fodder for the defense when you're talking about adults.

Defense counsel allows the victim to play up how devastating and terrible the first event was and then you ask why did you return for a second and third interaction with this monster?

It must not be a great case if it's only being pursued as a civil suit rather than a criminal investigation particularly in the climate we're in right now where these allegations are taking much more seriously than in the past
