"I'm sorry to shock you, but you're not exempt. No one is invincible," she added. "It doesn't matter what their SAT scores are or what they want to be when they grow up."

The fact that only three or four rapes are reported at Harvard each year does not mean that more do not happen, Koestner said.

Responding to a question from the audience, she said Harvard could provide better support for rape victims by developing clearer rules and policies and improving resources for victims and assailants.

She also encouraged students continue to speak out about rape and against rape.

"I know the students who are wanting to make changes are feeling alone and tired, and they need your help," she said. "Please keep talking about sexual assault. When it is quiet, we allow it to happen."

Although a majority of the audience was women, there were almost two dozen men in attendance.

"It's really important, although TBTN is primarily a women's issue, to remember that sexual assault can happen to both genders," Lee-Sean Huang '02 said. "It is great to see that there were so many guys here tonight."
