Considering he is one of four people selected and there isn't any evidence that the other three were of Asian descent this situation seems to be the result of him playing the race card when he doesn't want to follow the law.  Even after he was forcible removed he forced his way back on board.  Given his conduct, it seems his claim to be a doctor with patients he needs to see was a fabrication just to stay onboard.
I know it is Chicago and not Kuala Lumpur but any chances he's on the run from Kim Jong Un?
