I don't think the issue of information dissemination after an accident is nearly as cut and dry as you guys make it out to be. Clearly the agency has an interest in protecting themselves and therefore cannot be blindly trusted. The agency did the analysis, therefore the result must be considered suspect. Since we don't have an impartial third party with funding to do the analysis, the next best thing is information dissemination.
Accident voyeurism is real, after all - we are humans. That does not mean that there is not also real value in the details. That people are interested due to voyeurism and therefore we don't need the details is a non sequitur.
Future students are going to put their lives in the hands of instructors. Trust is critical there, because as students we are doing trust me dives until we get certified. Even after certification, we're trusting that the instructor, as an extension of the agency, trained us in a way that will help us to survive in the environment we choose to dive.
The scenario described in the first post could have been easily avoided by having an additional instructor already in the cave or by using another cave or at least by having someone run a darn guideline for the student in advance. It all just sounds like such a massive amount of stupid that the agency not finding the instructor at fault is hard to fathom. I'm no instructor, but there's several violations to what I was taught on day1 of cave1 that it definitely makes me wonder about the quality of IANTD's cave curriculum.
Maybe we need a kickstarter to fund a nonprofit accident analysis organization. Or an endowment from a wealthy widow or something like that. I know there was an awful attempt at such a thing once, which was then ruined by the organization using analysis to try and sell their own rebreathers. Don't let the idea die because some jerk got greedy! Surely if $20 million can be raised to fund a smart watch project, sufficient funds could be raised to start such a nonprofit organization. The Californians managed to fund a nonprofit chamber when it was needed. It CAN be done!
