That a upper tier college like Duke washes its hands of student behaviour like this, or worse -- going back to the Animal House days, but not much before those years, and even not as big then -- is a factor to liability, imo. And I bet that at some point those young near-men and slightly more worn ladies of the drunken nights take on a swashbucking legal team (to use a metaphor from the last scenes of AH) and take a run those ivy ramparts, major endowments and deep pockets a major U like Duke has.
