We live in different legal systems. Sometimes I also have a lot of questions about the laws of the United States, because Trump has signed a lot of executive orders to ban Huawei and TikTok, without going through the court or Congress, and they are effective.

Back to Hong Kong, the Hong Kong National Security Law is not retroactive:

> Article 39 This Law shall apply to acts committed after its entry into force for the purpose of conviction and imposition of punishment.

The police found evidence that he violated the law after the National Security Act was released, so they arrested him. I wait for the Hong Kong police to release more information.

YouTuber is just one of my information channels, and I also go to the websites or forums of protesters.

Well, I live in China, so technically we don't. You can say we were born under different legal systems. In China, law is often a tool to punish those the state doesn't like.

Trump hasn't banned TikTok yet, and the powers he is trying to use for that were given to him by Congress. It hasn't gone through courts yet, though, so you need to read more about it before making claims. This seems to be a pattern with you.

They claim it is not retroactive - but I highly doubt it. And you yourself said he was being punished for things that happened before it was in place.

The President has emergency powers in existing law to regulate foreign trade in this general way, for the purpose of rapidly responding to action by hostile foreign nations executed through trade including through notionally private firms.
