just gonna put this here:
1.) university police, most of the time, are sworn in police officers, not security guards.
2.) as the student was living on campus housing, technically he holds no right to ownership, so demand of and procurement of a warrant to him personally is meaningless. universities are allowing the search and seizure of property in dorm rooms without a warrant, otherwise known as "health and safety" searches when probable cause is seen fit. most of the times, these searches are agreed upon by the student when they sign any contract allowing them to live on campus. whether or not the findings from the search hold up in court vary, however, depending on the constraints and concessions put in place by the housing agreement.
MA Supreme Court Case Commonwealth v. Neilson which is cited frequently for campus dorm search and seizures states "not only the general validity of such a housing agreement for Fourth Amendment purposes, but also the limits to which searches conducted under such policies may lawfully extend."
3.) didnt help that this kid was a spoiled pungent puke. if he would have only respected the officers instead of call them names, point out physical attributes, and use foul language he may have gotten away with it. plus if he had no alcohol, then he should have just allowed the search to take place then file a complaint the next day if he felt his rights were violated.
there's my 2 cents.
