With regards to hazing cases, you might considering checking out the following anti-hazing site.
http://www.stophazing.org
The author of [italics]Broken Pledges[/italics] moderates a mailing list that posts articles and briefs on accounts of hazing. The hazing list isn't limited to just greek cases of hazing. What is interesting to note is recently most of the articles (some are about the same insident) have been related to athetics rather then greeks.
