The whole problem with your hypothesis is that they weren't cops! They were security officers. No power to arrest.

And who told you that? This article says they were police. Why else is the Mayor of Chicago bitching about the incident?

Mayor Rahm Emanuel said the suspension of the three officers were handled well by Aviation Commissioner Ginger Evans.

So now i've provided some evidence that they were police, so you go ahead and counter it with some evidence that they weren't.

Then we can figure out which one is true and which isn't.

This article also says the were Chicago Police.

There are police. Just not members of the City of Chicago Police, though they are city employees that make $50-80k. It’s just that they do not have to meet the exact same standards as regular city police.

How about this!

The aviation officers who dragged Dr. David Dao off the United Airlines lane—are not police—they do not carry guns and that day at least one of the officers had the word police on his uniform.
