Rule 1 -- Don't argue with a cop. Any cop.
In this case, get off the plane peacefully and sue everyone later if you think you were wronged.
It wasn't United that beat or dragged him, it was 3 Chicago Airport cops, doing their job. Maybe not well, but there's about 300 of them policing O'Hare and none of them are armed. Since they can't pull a gun on you to secure your immediate cooperation, it makes them more likely to engage you physically .
If he'd cooperated, he might have a nuisance lawsuit. As it is, he'll sue and probably settle for next to nothing since he refused the lawful order of an actual cop and then fought him. Good luck with that cause of action. The result will probably be sealed by terms of the settlement.
This guy is not a doctor, he's a convicted felon. Convicted in 2005 on multiple counts of illegally prescribing and trafficking painkillers and lost his medical license. He became a pro poker player in 2006. Hasn't been a doctor for 12 years.
While no cabinetmaker in his right mind overbooks his production schedule intentionally, the customer's recourse is his contract regarding delivery and penalties, if any, for failure to deliver under the terms.
Not to have a physical fight with the cabinetmaker or the local constabulary who might show up to remove a belligerent customer from your shop.
United and probably all carriers are no doubt reconsidering how to handle these situations. So is Chicago and their airport cops.
Obviously, United could have handled this better, more money would have coaxed a 4th passenger off of the plane to accommodate United's personnel. But, it's their airplane, they can do as they wish under existing rules. And they did.
Just as nobody can walk into your shop, even after being invited by you and then demand that you build his cabinet, RIGHT NOW, even if he's already paid for it.
This is all a tempest in a teapot because this convicted felon is a very, very large jerk.
Early today, people all over the place were jabbering about how UAL is down 3%. LOL. It closed down about 1% at $70.71. Sorry, no collapse.
UAL has traded between about 65 and 75 for about 5 months. It's about $5 off its all-time high and sells for 10 times earnings. In other words, cheap.
Not that it can't get cheaper, but if it paid a 3% dividend I'd buy it and write a January 2018 call option for $5.00, take my ~$7.00 of income and just own it. But they don't, so I won't.
If you look at today's price action to see if anything significant happened yesterday, you'd have to say no. Just another insignificant jiggle.
The economy took UAL down to about $3 in '09, but today it could fall to about $40 and its strong uptrend would remain intact. They don't look like geniuses today, but they are the 3rd largest air carrier in the world and somehow, despite their occasional stupidity manage to do 36 billion of gross rev per year.
A few weeks from now, everybody will have forgotten about this clown and business will go on as before except the rules will be better for throwing a jerk off of your airplane.
Now, perhaps back to Yelp, an outfit I would avoid for the reasons above, having heard a few similar stories and reading reviews that I know are bogus simply from having been at this or that restaurant, for instance.
I would write Yelp a very nice, civil letter and tell them that the review(s) are false and defamatory. That unless removed you might sue them and subpoena them and their ISP to produce the identity of the defamatory poster(s.)
They know that they and their ISP can be forced by a court (via subpoena) to divulge the identity of the poster(s) who made the allegedly defamatory statements.
That you would then be able to depose the poster(s) under oath regarding their defamatory statements made about you on the Yelp site.
Yelp also knows that if all of that happened, the poster(s) would probably voluntarily withdraw their defamatory statements, not wanting to be sued for their folly. Knowing that they are already in the middle of an expensive legal battle. Over whatever defamatory things they said.
Yelp likely doesn't need or want all that possible aggravation.They might decide that it would be a good idea to dump the garbage and save you all the trouble and expense. Not to mention themselves.
Not bad, if all you have to do is write a nice letter detailing your possible future actions, depending on their behavior. Sort of the squeaky wheel gets the oil principle.
You just have to be a little bit squeakier than the rest of the wheels that seem to get blown off routinely.
If they don't dump the junk, then you have to be prepared to spend a lot of money to force them to do it, because you certainly can if you can prove the defamation.
But, alas, it's rarely worth it. What with lawyers and all not being free.
And don't ever threaten any legal action that you don't fully intend to follow through on, that's a form of attempted extortion in some jurisdictions.
And always, ALWAYS get the advice of a lawyer before you do anything along these lines, even sending a nice letter that might mention possible legal implications.
If you look for a lawyer to do a review of any letter or other options you may have, I'd ask any lawyer friends whether they or any lawyer they might know has a particular or even generalized dislike for Yelp. Might result in bargain rates.
