just FYI - the gent recently interviewed by Der Spiegel (Fred Westerbeke) is a CRIMINAL investigator alias prosecutor, and he does NOT work for Dutch Safety Board..
So whatever he says in public about the case, must be bullet-proof alias backed by hard facts and evidence.
Trying to illustrate it with analogues from CIS space (aka SNG):
Dutch Safety Board (DSB) at least as far as aviation is concerned does the same what MAK (Interstate Aviation Committee) does in SNG area (minus Ukraine apparently now).
Mr. Westerbeke, on the other hand, works for law enforcement (investigative branch of it), which probably best compares to 'Genprokuratura' (in recent past) or 'Sledstvennij Komitet' (nowadays) in Russia.
