It appears that BEA head Remi Jouty never said what the Guardian and some others have reported he said ruling out decompression. The transcript here -
http://transcripts.cnn.com/TRANSCRIP.../25/se.01.html - is questionably translated or perhaps he was terribly clear, but he was declining to speculate, not denying the possibility. The translation would have to be incredibly for his actual statement to be a statement that there was no decompression event or no "classical" decompression event.
