You are again trashing the victim - describing him as weird. Strange he ran back into plane? - yes when someone knocks you out and drags you in front of 100 people and you probably suffer concussion and are totally dazed, you do act "Strange" . Oh and he should provide you his whole medical history
The only thing strange and weird here are the questions you are raising.
It's hard for CB not to take the offensive stance because he is after all working with the same airline so there is an inescapable sense of internal camaraderie and informed network. The impression of believing the industry knows better than the layman, the desensitisation of the outside schema, is not exclusive to aviation though. The medical professions have it, teachers have it. The higher the knowledge landscape the bigger the perceived gap.
We have a 69 year old manhandled by three officers, dragged to the ground with a hit on the head. We don't know the extent of his injuries when being pulled out of his seat I can imagine at least sore muscles and joints being the senior citizen that he was. Dislocated shoulder, bruising, twisted wrist, all could have happened. Fortunately he didn't land on his artery or this would be a more serious incident that would have chucked all law out of the window.
To me this is an isolated incident that may likely not represent the industry or even the airline, but it doesn't help that many inside it who believes has been desensitised and it is acceptable on the assumption of law being enforced. Eyewitness accounts have shared how the airline crew who dealt with the whole process was the one belligerent and rubbing people the wrong way with how she handled the situation from the start, while the passenger even prior to being chosen was passive like any other passenger. CB also insisted that passenger agreed on the $800 but none of the accounts by eyewitness mentioned of this (
https://www.usatoday.com/story/news...ard-united-flight-removed-students/100327772/) or any written agreement for that matter as demanded to be clarified in the 15 questions query of the group of senators directed towards the ceo. It seemed from eyewitness report the man was reluctant to move from the moment he was chosen.
It is true that nobody is above the law. But when the law being used is inapplicable, everyone is above it.
Edit: This reminded me of the lawyer who was told to get out of his car by federal officers. He recorded the whole conversation, and being the lawyer that he was he knew exactly how he was above the law being applied at the time.
