I was thinking about the idea of universal jurisdiction. It was said that countries can prosecute people who commit war crimes regardless of their nationality.
A famous person says something critical of that government or its supported policies. In this hypothetical case, could that government order him to be sent there?
There was a Hong Kong security law that could apply to everybody on the planet.
That person did not violate any US laws. But they violated the law of a country that doesn't allow free speech or something along those lines.
If they wanted to arrest anybody (not necessarily who I used previously for the example), what means would they have at their disposal? Could they send in secret agents to transport the "criminal"? Sign an extradition agreement?
