Winnie:
The data you looked for that you didn’t find is quite difficult to find anywhere. Firstly, the subject here is about molestation, not other forms of abuse. Secondly, one would need a decently representative sample of all victims, and this is just about impossible. The ones who never report and never disclose are every bit as central to the discussion, and these would never have been sampled. The hesitation even in the general population to disclose is massive, and lead many of the researchers to recognize this in the inferences to draw from their research.

You wonder whether the history of being a victim might be a mitigating factor in the prosecution of a perpetrator. Firstly, I would bet that every defense attorney would try this defense. Logic is obvious. It converts the perpetrator into a victim, and that tends to gains clemency from a jury, and judge. It also suggests that the perpetrator acted on a biologically determined urge, not ordinary evil thought. That is also intended as a defense. I am not sure whether this actually works much in court. How often does the rapist push the agenda that the victim asked for the crime to be committed? Can’t speak for past history, but this no longer works at all in today’s courts. Ask around by some lawyer friends.
