The ticket is a contract and gives you standing in a civil court. The Captain says get your butt off my plane, then you go. Deal with it like an adult and not psycho retard.
The pilot was never involved.
1. I don’t see Dr Dao as a “psycho retard”, regardless of his prior legal history (irrelevant). 2. He was under no obligation, legal or moral, to accept his involuntary removal. 3. The captain was never involved in any part of the event. The pilots union, speaking for him, has said so.
