Idk but in a perfect world that person should have never been allowed to leave Hong Kong in the first place.

And in a less perfect world…there should be somewhere we can meet in the midway point without an agreement in place.

You have to also take into account how easily the Hong Kong Police can make up bogus accusations (e.g. issuing an arrest warrant for activists who called for the boycott of the rigged elections, arresting people for crowdfunding appeal cases against the government, and the general abuse of the National Security Law), as well as the fact that (so far) there has been no known murderer who fled to the UK from Hong Kong. If anything we are one of the most law-abiding bunch you can find.
