I agree about it being the mob. Didn’t Harry box in his younger years? Wouldn’t he have been able to defend himself from his little brother, especially with Secret Service guys around? If he was dealing with the mob, he wouldn’t have any SS guys on hand to witness the event & he’d be more likely to get hammered by a younger man.

He was probably a Flyweight. And he only boxed a little bit in school, as far as I can determine. Maybe the Mob is getting pissed because Harry is dealing too much with the Chinese?
