Regarding 'blame', 'agendas', and your ongoing discussion:
Its not about blame, though some will try to make it that. Its about finding causes, ops practices, and design flaws/weaknesses/errors and doing what it takes to never permit the same accident to happen again. In order to do that, root causes (blame) will have to be properly placed. This is not a murder charge. But it is fessing up to even the slightest possibility that some action/inaction may have led to the failure. Admitting such failures is personally and institutionally hard for any person/organization. But for safety of future flights it is essential that the failures be identified.

I had already read that and I agree with you.
Regarding the ongoing discussion, "we" are not the ones trying to assign the blame before all the facts are heard.
