Fraternities blamed for date rape drug

According to WKRN news, two fraternities at Brown University have been sanctioned for having “unregistered parties” where girls were allegedly given drinks with GHB (roofies) in them. Having been a college student once (I think I might have been at one or maybe two “frat” parties…) I am not sure that Brown University made the right decision in sanctioning these fraternities. Anyone’s thoughts are welcome.
