I agree. In Europe universitys expect you to be an adult capable of managing your life and don‘t involve themselves in it.
American colleges seem more like closed communitys with their own rules. Maybe that‘s because most of the time only exchange students live on campus.
College students are adults, so the most serious (and possibly violent) sexual offences can be prosecuted according to criminal law, and the rest is just something two adults should be able to figure out by themselves.
Cases like the one described in the article are simply impossible to be correctly assesed by the judge or jury: too little information, and all the reasoning rules that one could apply are subjective and culture-dependent.
