Stupid story. Grewal is a headcase. Lots of guys go through that and they don't spit at the camera.
Seconded! The sport got quite a bit harder at that level in manners that did not suit him. (motos with cameras in your face) No excuses for spitting. None. Clearly he didn't modify his behavior after the incident to satisfy his employer either.
Pumping up a compelling story so he can get some sympathy is enabling his kind of crazy. If the comeback can make him a better father, and get him into steady money, then go for it. But I don't see how it would.
IMHO, I think it's a distraction to keep his attention away from his big, difficult personal issues.
