Yes, police do enforce any company rules. In other words, if this was a bar, your home, a business and you wanted someone to leave, you can call the police to make them go. Its your property and you have the right to admit or not admit someone on that property. Also this is airline security which enforce you know airline security. Airline security is not part of United and their action actually is their own. Since United is the one that called them it's still their fault that the incident happened. As for the overbooking policy, you better check every airline because they all do it. Federal regulations actually allows them to do it and regulate how they reimburse customers for overbooking. |
He paid the ticket and United let him go on board. Everywhere else in the world, in case of overbooking it's the last arrived and not on board yet that gets shafted, never anybody that was already regularly boarded. He didn't board either sneakily or forcibly, United boarded him. United called the police, or the airport security, not to enforce a rule he violated, but THEIR violation of a deal they stroke with the passenger in the very moment they accepted to board him in exchange for his money.
