Full agreed. The release of such information to the public, by a head of investigation himself, is totally unprofessional and the French BEA deserves even more mistrust.
are you sure that is what was released?
it's one thing to release an actual recording for subjective interpretation by the public and quite another to release decoded spoken words.
For sounds other than words the CVR team typically paraphrases these into descriptions appropriate to the investigation in the language of the lead investigator You typically do not leave unstated a blank area in a recording unless it actually has no data.
What words that you use to describe an area in a recording that has sounds other than spoken words is the provence of the langauge of the decoding expert since you have to put something down on paper factually.
I'm not sure if it is the translated word "scream" that bothers you or that you would have preferred some other factoid in its place.
