"Controversy" revisited 

As a member of Phi Kappa Psi, I'm using my discretion and agreeing with everyone that it is irrelevant to the article. At my chapter, there was a rape back in 1990 that has all sorts of haziness and ambiguousness surrounding it, yet it's not included in this article either. These happen all the time everywhere, and as someone said above, we just don't have the resources to report every one. This is an article about Phi Psi's history, statistics, and ideals, and not the place for one random, disputed incident that happened years and years ago. 
Imagine it this way... can you see this part showing up in Enyclopedia Britannica? I don't think so. If need be, as stated before by someone else, create a new article if you're dying to get this out to the public, or even add it to the UVA page. But there's no need for it here.  Amici ~
