there is a tangible disinterest in prosecuting this --as well as most-- sex crimes in the united states. In many US states, rape kits used as pivotal evidence during trial are backlogged and processed at a near glacial rate or lost entirely. Bill Cosby and Harvey Weinstein are examples of a situation where power in the united states, combined with a longstanding puritanical distaste for sex, culminated in a decades long failure of justice.
even the very protections victims receive in US courts are a mark of our inability to approach sex itself with a mature demeanor. we'd rather soldier on in silence, discipline, and remorse than honestly atone for real crime. that a victim themselves may succor the courage to face their attacker in court, is such a vicious affront that we're given no choice but to prosecute or lose face.
