Jimmy Lai didn't even bother to conceal his involvement by directly deposit so many money towards many opposition politicians' bank accounts. Basically before the NSL, nobody in HK bothers or dares to go after the money trail. As of now, most of CIA and middlemen have left HK. I am quite doubtful there would be a significant breakthrough.I really hope they reveal the evidence of the funds collection.
The MSM might not like the laws of the HK SAR, but the procedures have been totally above board. Even the foreign judges still in HK say this. This means the evidence is more than likely very strong.
