Exactly. DFDR and CVR are. This is where any meaningful and reasonable discussion regarding their use in judicial process ends.
Of course I disagree completely the idea that you made of justice
BEA conclusions and recommendations are there for improve safety
DFDR and CVR were witnesses at the scene of the accident
As in any trial .. if there are witnesses .. the judge and lawyers want to hear their testimony .. not for make recommendations .. but for find if anyone or anything can be responsible of the accident
Now .. if the judges in charge of the AF447 accident don't request (or are denied to acces) the DFDR and CVR .. it's a denial of fair justice ( put away two important witnesses)
In fact .. without the DFDR and CVR ... a tria is useless or at least a truncated trial
A simple example is that of a bus , train or truck accident
They are also equipped with a black box
And that will be part of the documents examined by judicial experts and judges
