Was the procedure to be that a representative of the French judicial police, and representatives from the UK, Brazil, Germany and maybe the U.S. would listen to the CVR along with the BEA?
If so, it would be as some of the comments in Le Figaro exclaim, 'Extraordinaire!' to have the BEA come out with findings so quickly. And to presumably do so with the concurrence of the French magistrates conducting the criminal investigation.
Under French judicial procedures, if a party under investigation is determined not to be at fault or involved, must the court quickly remove that party as a subject of the investigation? Perhaps that is a reason for the speedy release of the findings.
