I'm sure the same arguments were made when CVR / FDR, and QAR's were suggested (WHAT !!!? ATC record our R/T ??)
Put into context, the value to help explain the causes / contributing factors to the long list of unexplained / unexplainable events, must outweigh the civil liberties fears.
The emphasis should be put on the correct procedural control of the data, as with all other sources, and while there will always be 'leaks' the efforts should be put into minimising these rather than stopping a system that could, and most likely would, save lives and improve procedures and cockpit design issues......
I can't quite see an operator releasing it's "Worlds Scariest Cockpit Video's" to prime time TV ! (Hmmm maybe a franchising opportunity here......)
