The authority of command comes with responsibilities. The travelling public will not put their lives in the hands of blind trust anymore.
The Coster Concordia accident is a good example of the great public displeasure that follows an accident.
Cockpit video, routine CVR monitoring and rigorous drugs and alcohol screening are the sort of compliance monitoring tools that the public will demand.
Or
They will insist that crews face the full weight of the law for endangering aircraft when accidents of near misses occur and treat errors as grounds for manslaughter charges.
Your call.
I think it more likely they will be told that such compliance will raise fares. Demands for such things will then go away.
