This man was removed from the flight then, somehow, got back on the plane. It looks to me like this was planned with the purpose of a lawsuit. He was on his phone with his lawyer as they were approaching him to remove him the second time, telling him to get a lawsuit ready.
“It looks to me like this was planned with the purpose of a lawsuit.”
You are in total error. His name was picked at random after everyone was boarded, and he had nothing to do with his name being selected; ergo he could not have been planning a lawsuit when he boarded.
