You have a lot to say about this one man's responsibility for his own actions, but not nearly as much about the crew or the officers' showing responsibility for their own actions and finding a way to de-escalate the situation without resorting to crudely manhandling and dragging someone off the plane, just because the airline screwed up their own internal scheduling and somehow had absolutely no other way to provide 4 crew worth of manpower on another random flight with no rationale given as to why it had such priority as to employ the use of force to remove paying customers on another flight if necessary. Cuz, you know, that fourth guy...absolutely indispensable or something.
But yeah, let's just focus one man's responsibility for his own actions, because it's all on him how we got here.
