Whomever said it apparently Cates was there and didnt offer up any dissent, so obviously it was something agreed upon earlier.
This practice is no different than the parent handbook indoctrinating parents with; "your child will lie to you, will tell this is an awful place, don't listen to him."
I have no doubt that the counselors frantically called every parent to tell them some make believe fairy tale about what really happened, they probably also told them "There's a bunch of rumors(aka "the truth") going around about this event, if your child tells you anything don't believe him and please report it to us."
Manipulation down to a science.
I'm going to guess but I wonder if the counselors bothered to mention that the girl who actually performed the rape stayed on campus for another month.
Sure sounds safe.
