I think there's a tendency to be a little harsh on National. Remember that when someone comes forward with allegations of hazing, whatever is said is kept in the strictest confidence.
I read this to mean that whoever reported the hazing does not want their identity revealed to the chapter, the university, or anyone.
Now, I've personally had a candidate turn me in for hazing (this was back when I was L.C. of our colony). This, of course, was clearly retaliatory in nature because the E.C. and I had just run this guy out of the colony (long story).
He and his mother called IHQ and complained. I have no idea who they spoke with. Our expansion director at the time gave our E.C. a call and informed him that this was probably the most hilarious phone call they'd received at IHQ in some time and not to worry. In other words, based on this experience, I'm going to think that there has to be something more than the word of a single candidate to bring down a Rock Chapter when the same thing couldn't even bring down a colony. What I'm saying is that the evidence National has must be pretty substantial to merit the responses with our Kansas and MTSU chapters.
That same kid went to the university administration as well as I think to the local authorities. No one ever took him seriously. Poor guy
