The difference between Haddon Cave and The Trainers Letter is ownership. Former is CX/swire, latter is now public record.
Recall, only choice portions of HC were released. When and if an event/incident (please no!), occurs then the shredding machines and defrag utilities will be running hot. However, like the 49ers it's inevtiable; what turns up from a disgruntled employee/manager at later dates may become of some concern too our current directors and managers.
Could RH become the fly in the ointment, ala wilkinsons sword. Oh the irony of it all.
