I know, and that goes to show how previous CPC leaderships failed to implement even the most basic form of national security measures and how they aren't perfect at all and could lose some rounds. The CPC was fortunate that Xi Jinping made the correct moves to eliminate such a threat. However such a threat should have never been one to begin with.To be fair there was nothing the MSS could do. Beijing failed to subvert HK politics to implement a national security law and education reform. Hong Kong was a funny place before the NSL. In Europe if you have a few thousand Euros in your account that you can't/don't explain its origin it can be confiscated as a crime money. If they were already investigating you for some reason it would become evidence against you. In HK, Nathan Law to went to HSBC with hundreds of thousands of USDs. Nothing was asked.
