The leaked CVR is an obvious fake unless the Prosecutor was lying.
On the subject of an investigation releasing facts or evidence during or before a final report...
I do not see any reason that non controversial evidence should not be released. The idea that there are issues of privacy involved in the case of an air accident is ridiculous. Neither does it seem to be offensive to grieving relatives of friends, although some people may disagree. In my own experience more information is better than less when coping with grief.
Wild allegations and theories on the other hand are no help to anybody.
