I have never read the 11 page thread refered to.
So the abused wife or child on the J/S waits for the other Pilot to leave for a call of nature. Stabs family pilot with nail file, after all he got her aboard, stangles him with his own tie and kicks the post forward. Could just the same be an employee fired 30 mins ago. Flight deck locked for the sake of all aboard.
Wait till all Pilots vetted 24/7............................
