In the US, way less than 50% of the women who are raped ever go to the police, for various reasons, some of which we have read here on this thread.

I recommend all women, if raped/assaulted at their organization and/or by someone in their organization (school, employer, etc.), they should IMMEDIATELY call local law enforcement, and, after that, then inform whomever in their organization. Usually, HR at their organization will not help them at all.
