Also, I don't know of any law that says that what the police are looking for in a search warrant has to be there when they do the search. If it ain't there, it ain't there, and they can't make you produce it from another location without a separate search warrant specific to that location.
I seem to recall that the lax players had moved from Edens prior to that anyway (which was, of course, why Collin's stuff wasn't there); but I could be wrong. I can check with my student later. Certainly the dorm was locked to outsiders (meaning, only Edens residents could gain access - ususally your Duke Card will gain you access to most any building). Ugh. This just brings back how awful that time was for the students.....
