I can honestly say, in my fraternity, rape prevention was never on one of our meeting agendas.
Honestly? In-house risk management can be good to extremely poor depending upon the chapter. It was pretty good at ours at KSU - which, by the way, has a relatively well-managed and tame Greek system. These are 18-22yo males with often far too-little supervision. And college women also seem to be getting dumber and putting themselves in riskier situations when it comes to parties, dress, drugs, and alcohol. It terrifies the general fraternities. They're constantly trying to recruit alums to come in and provide guidance - especially risk management. Women and alcohol are literally lawsuits waiting to happen.
