That's not what I'm arguing. The word "responsibility" was probably a poor choice on my part and I'm still having trouble articulating my point of view on this. The overall point I'm trying to get at (I think) is that this kind of adversarial relationship between students and administration over behavior has existed for centuries. The traditional role of administration is to regulate behavior of its students (for a wide variety of reasons that are not necessarily Puritanical) and the traditional role of students is to subvert the administration's efforts to curtail fun misbehavior. Of course students don't have a responsibility provide plausible deniability to the administration. What I'm really trying to say is that the two groups have different interests when it comes to this kind of behavior and that in a healthy campus culture that is both academically and socially stimulating the cat-and-mouse conflict between those two groups keeps things in balance for the most part.
