I think you are missing something, and in doing so, appear to be sliding into what you yourself have bemoaned. This is not adversarial to the extent of being fatal to any argument. There are POV's as well as ROV's.
BEA is a closely connected agency with the principal interests in French Aviation. If you wish to promote the view that all is objective, independent, and scholarly to the exclusion of bias, we should talk.
If however you take the view that there is a history of adversarial and parochialism re: these issues, no harm, no foul.
It is legend that aircraft carry with them certain reputations. Are "Experts" hobbled with some of these prejudices?? Of course. LKP was the beginning of the problem, and the airbus cannot fall straight down, nor can it lose bits, so "we" plan accordingly, and perhaps reject preliminarily some critical data.
