I think its more to do with blame CoolP, if you remember with Capt. Sullenberger he had to/was forced to accept the blame for the Airbus sinking so quickly s under the pressure he forgot to press a single switch before leaving the cockpit which caused the aircraft to sink a lot quicker and putting the passengers at risk. Any pilot that has alcohol in their blood after a crash will get the blame no matter how much they had the night before imo.

Recent changes to European law is there to put more blame on the flight crew if something goes wrong as making the pilots working day and working week longer is meant to be safer and fight pilot fatigue better but i dont know how that is meant to work.

edit, here is that episode Fedex 705
