The British lawyer might have more relevant training among western lawyers depending on how old he is and if he dealt with old HK law. One needs to conclude that either no HK lawyer is willing to take the case (perhaps due to fear of retribution) or the westerners think it would be a bad move (for example, if a HK lawyer simply tells the truth to Congress and does not get punished back in HK). I'm just speculating, though.
