This is where I stand. It makes no sense to file a civil suit against him as a student when he has zero resources to lose. She attempted to get some type of justice through the criminal system, which failed at the time and this is her last chance.
Also, she did report the encounter as a sexual assault hours after it occurred. It's not as if she's making it up now out of thin air.
The truth is that the only people who know for certain what occurred are the young woman and Hairston, and even then, two people can have very different perspectives on the reality of a given event.
