Actually Glueball,
I think you are wrong, there are plenty of cases of closed courts where the witness or victim is being protected.
Furthermore, there are plenty of other secret courts where really odious things are done like wiretapping and bugging that are not open to the public either.
Don't be so sure that all that is coming either. If this gets out to open court and the families of the crews get to hear their husbands/fathers being murdered on the 6 oclock news, I think the CVR may be finished.
The increasing trend toward criminalization of aircraft accidents is already putting pressure to REMOVE cvrs.
Cheers
