Right. Airline must keep lots of ‘ready-to-panic’ people calm and under their control and was happy to take that role. You really don’t have any rights flying because of that confined situation where the flight crew must remain in complete control.
I was just replying to nimrod OP who wants to make it look like a bad cop. When the cop called in board must do what the flight crew says. If they want you off because you’re too loud, you gotta get off. We don’t see the whole vid or what he did to make the flight crew demand his ID. But she is the boss of him as soon as he boards. Period. And the boss of the cop she called on board. What she says goes or he gets off. Yes he doesn’t have to show his id by law. And then by law, as the consequence, she can have him forcibly deplaned. Simple as.
And that’s the law we allowed to happen because we want to get from A to B fast
