I think Bose-X sums up my personal view very well
It's all very well for the hand wringers to ask for everyone to wait for the formal reports, but these often take years to be published. In the meantime, somone else could be making the same mistakes that have resulted in an accident. If discussion and 'speculation' makes pilots think about all the things which may have caused the accident, then it's surely in our own interests to open up the debates.
