Here's one: (In which the author provides two reference links.) It is an opinion piece, not a report or a investigation, however. IMO the author makes a perfectly valid point there, with reference to real world outcomes. I read it as her saying: "perhaps these rules are not resulting in their intended outcome", or "perhaps these rules are resulting in unintended outcomes in addition to their intended ones." I don't see that as rhetoric, but a perspective drawn from some evidence that supports it.Sometimes, the movement’s supporters claim that the new rules amount to little more than common sense: Don’t have sex with someone who isn’t a willing partner. In practice, a male student at California’s Occidental College was recently expelled for having sex with a woman who was willing and enthusiastic, but apparently too intoxicated to think clearly.
