If this is true, by all mean he should be punished.
The thing is, this video screams dramatic monologue to me. I've taken many acting classes, and this sounds like the work of an amateur acting student. The way she is putting emphasis on certain words and building intensity with her voice sounds exactly like someone who is studying acting. Also, she said she was 19 at the time, but her voice sounds like she's going through puberty.
And please don't tell me that I'm being a Misogynist. I'm skeptical of this video, but I'm not saying it can't be true. Rape is a really strong accusation that can ruin a persons life, even if it turns out not to be true. There is a very big difference between sexual harassment and rape, and sexually harassing people doesn't mean he is a rapist. As I said before, if this is true, then by all means throw his ass in jail, but he is innocent until proven guilty in my eyes.
