Reading the reddit postings. It seems that the person brought this out to the corps a year ago. The corps appears to have done nothing based on the facebook post acknowledging that information was made public. That might leave the corps liable for civil damages if this person goes that route.
What if this was an incident from further in the past say 30 or more years ago, and the staff / BOD members today were part of people who had abused other corps members. Should that information be made public? What if the person or persons abused were still dealing with the pain even today?
