Here is what we know also far about the investigation:
The investigation report issued on April 29 revealed a persistent series of deeply troubling activities within the fraternity. These activities included photographing individuals in extremely compromising positions and posting these photos to a private Facebook site accessible to the group’s members. Several instances of hazing, which included physical and emotional abuse, were uncovered, as were drug use and sales. And the investigation brought to light the persistent harassment of two female students, who were degraded through multiple postings to the organization’s private site over an extended period.
Personally, I think that Sims is a turd, but assuming that he correctly characterized the investigation's findings, I think that Penn State was right to suspend KDR.
Boys will be boys, but if a fraternity isn't teaching those boys to act like men, then it doesn't really serve a good purpose.
