Extraterritorial jurisdiction is becoming increasingly common. If a person commits a crime in a foreign jurisdiction they are convicted, and then when they return to their homeland they are once again convicted for committing a crime abroad.

I know the UK and USA definitely do these prosecutions regularly, even though both countries would throw a hissy fit if Iran started prosecuting every tourist who visits and was known to not wear a headcovering outside Iran.
