I agree that it's not a good thing to put yourself in a bad situation, but I don't see where it says she was drunk. this is where the incident(s) is/are described:
Among the thousands of pages of documents gathered by Missouri administrators in late 2012 in response to a records request was a December 2010 online chat transcript between Menu Courey and a rape crisis counselor that had been saved in Menu Courey's university email folder. In the transcript, the former top swim recruit describes an assault after having consensual sex with an unidentified man. Another document discovered by a university hospital administrator shows Menu Courey had told a campus nurse and doctor in 2011 that she had been raped by a football player in February 2010.
too often it seems the authorities look for an excuse to do nothing, instead of just blocking out the heat they know they'll take from players, fans, coaches, and even University officials, conducting an investigation, and filing charges. DAs are too political sometimes to pursue charges knowing it's going to hurt them when they go up for re-election, and the biggest employer in the county (Mizzou), it's football team and their fans, are not happy with them.
