> we should never directly challenge the request of anyone in a position of authority because we can then address it in the courts later in a fair and civilised manner...as a blanket statement that it's always better to obey, no matter what the request seems absurd.
You are arguing for the use of violent resistance to authority. If you disobey an authority what do you expect to happen? We have the right to peaceful protest, a democratic government, and a justice system. The only alternative I see is a violent confrontation with police which is not the society I want.
> To my mind the actors who created a physical altercation were the police officers and not the passenger.
You cannot disobey the police. The physical altercation was most definitely created by the passenger refusing police orders. I like US police because they get the job done. If this was Europe it would most certainly have been a different story. Plane would have been endlessly delayed, etc.
> To me their options are clear, persuade one passenger on the plane to get out, or lose whatever amount of money they were going to lose by not having that crew on their plane.
If you leave one passenger on the plane, you give reason for every other passenger to refuse. Then what do you do?
I would have given the same order to remove him from the plane with force, and I would expect this to be carried out like so. If there is some sort of mistake, it can be cleared up afterwards without inconveniencing everyone on the flight.
To argue against this is to argue that no one should ever be forcibly removed from anyone else's private property. The argument clearly does not hold across different scenarios. Follow the police's orders and leave someone else's private property when ordered to is a consistent message that makes it easy for everyone to avoid violence. Allowing everyone to live by their own interpretation of the law ends in more violence and regret.
