as they might still be subscribed to puerile notion of improving safety via legal punishment.
The judicial court is not there for improve safety ( but can still contribute if it punish persons or entities who have breached the duty of safety and so removing them from the loop ) .. the court is there for define responsabilities .. name the culprits (if any) and give punishment as required by the country laws in force
And for make this ( dispense justice fairly ) .. the judge (s) and lawyers need to have all evidences and expertise at hand
When judging a crime .. the judicial body will not examine some evidences and not some other .. this will be unfair ...
Idea is that investigators will duly report suspected criminal activities they come across and judges
This is the job of the judge to decide (after hearing all parties and with the evidences at hand) if it was criminal activities resulting of 228 dead ( before .. during or even after the accident)
And if the judge require the entire CVR for the need of justice .. he will ask for have it .. and his request can be positively answered ( Ref .. canadian court concerning AF A340 Toronto)
This does not mean that the entirety of the recording will make way to public
