I have yet to see a picture of the goons that dragged the guy off the plane. I am curious what they look like.
Drive past the entrance to a strip club and you'll get an idea...
This video shows one of the men who spoke to him before the physical altercation took place. It’s the only one where I’ve seen any photo of the authority figure. Often these show everything but the face of the person.
