Wino & Glueball:
Your points are well taken.
Perhaps an analogy with medical oversight is appropriate. Surely some barnstormers refused to bend (over) to the rules, but eventually such exams came to be the standard and some even think it is a good thing....
One way to put a threshold on indiscriminate distribution of cockpit video and audio is to record the original in a non-standard and/or encrypted format that cannot be reproduced without special equipment and codes. Control of these allows for a strict chain of accountability, at least. There's still no protection from damn fools and politicians, but unauthorized access won't happen without somebody's tail on the chopping board.
