The author herself describes a situation where she pressured someone into sex. Based on her own admission, there is little doubt that the man was a victim there, but to what extent should she be punished, and what constitutes adequate evidence before punishment should be applied?

If the victim went to the police, I would hope it is punished it the same as any other rape. Evidence is always a tricky issue. Proving that the encounter occurred is not enough, and without the physical injuries that can be used in violent rape cases there isn't much to go on. The majority of rapes don't end up getting prosecuted. I don't know how to change this aside from making sure that police are take victims more seriously.

IMO failings in these policies reflect that they originate in institutions that are often liable for damages in cases of assault.

Yes I can definitely see this causing issues. I'm not sure how this can be easily resolved though. More surveillance I guess, but I don't imagine this being very popular.
