I don't understand why you would not just provide more specific facts, if these events happened. As a result, some will doubt that they really did.
The protocol as I understand it is that ADR (Alternative Dispute Resolution) may be pursued before civil action, but you certainly don't have to.
Did any civil action get as far as a trial or was there a settlement before that point? What was the case number and at which court?
How about a scan of any settlement correspondence or the judgement, with names blanked out if you like?
