Re: Not unusual
@martinusher - You can't assume that you know which particular activities precipitated the law change because it was decided by the National People's Congress Standing Committee (NPCSC) and promulgated to Hong Kong without any debate or public consultation. You (unless you happen to be a member of the NPCSC, are you?) and I have no idea why they decided on this course. The trigger might have been violent acts that are also illegal in the UK and US - and illegal under existing HK law, although there seems to be some selectiveness in which cases are investigated and prosecuted (take a look at the 7.21 Yuen Long attack, or the IPCC report). Or the trigger might have been peaceful protests by over 1 million people, activities that are legal in the UK and US, and were legal in HK.
There has been a lot of talk about overseas funding, but the claims have not yet been backed up by evidence in court.
If the HK Police have shown leniency, with the claims of violence and sexual assault, compared to the US Police, then it just shows how much the US Police need to improve and learn lessons from the George Floyd case.
