Being in aviation claims of all sorts including pax liability, UA(well, their insurance company)is going to get crushed on this one. Attorneys are probably camping in front of his house now since the video is viral, and they see an innocent physician being man-handled like a sack of rice, blood on his face. Oh an American jury would tee-off on United if it ever made it to court, multiple of eye witnesses to take the stand for the plaintiff, so UA will throw big money at this one to make it go away.
