Hi,
They are not laws.
Hence the
"laws" in my post.
BTW .. in the case of exchange of informations about a accident this must be a law and not simply guidelines or recommandations.
How does a participant survey can work peacefully and with efficacity if they don't receive any evidence that the other(s) has ?
Is this the way to investigate the causes of an accident and thus have opportunities to increase security?
I think it's a mistake to allow (for the abscence of laws) competition or animosity among the different parties involved in an investigation.
