That's pretty far off on basically every point.
There's no such thing as "using false pretenses to assault and batter someone by proxy". If you have authority to ask someone to leave, and call the police to enforce that, you have no control or responsibility over how they go about doing that.
Regarding "lying to police" and "filing false police reports", all the police need to be concerned about is that he was asked to leave by someone with authority to do so, and refuses to leave. Airline pilots and other such proprietors generally have broad discretion to require people to leave. If he has a contract that requires him to be transported, then he has a civil claim against the airline, but the order to leave by the captain is still entirely legitimate.
It is also not the responsibility of the police to investigate the reasons behind a request to leave and determine if they are legitimate or not according to contracts. The law recognizes that the courts are for making real determinations of facts, officers on a scene have broad discretion to do what appears to be the law based on the information they have at the time. And in this case, they were entirely right - the crew does have the authority to demand that someone leave and does not need to justify that to anyone. Failure to provide the service under contract is a civil claim to be addressed in court later. Or, the short version, this classic applies - you can beat the rap, but you can't beat the ride.
I really don't get the need in these media sensation cases to burn everyone involved at the stake. Isn't it bad enough what United actually did wrong, which is to have a dumb policy for how to handle overbookings and crew transport? For nobody to look at the situation there and step back and try to find someone else more willing to take another flight?
There's a reason why we have due process instead of lynch mobs - the next person to make a mistake and be the target of the internet frenzy could be you. If you make a mistake someday and it gets blown up on the internet, wouldn't you rather face a reasoned punishment for the actual laws it can be proven that you actually broke, instead of having your life completely destroyed because everyone's really pissed off?
