"Crime" is something that means different things in different countries. Or rather, what is illegal differs between countries.
I think what parent is trying to call out unfair, is someone getting arrested in one country where something isn't necessarily proven to be illegal, then taken to a different country and prosecuted there, even if you're not actively involved with that country. Things like drug trafficking arrests are made by either the receiving/sending side (either way, local border control and/or anti-narcotics police) of that particular transaction, not by some other party half-way across the globe, because it isn't really their responsibility.
But then I'm sure you can make the argument that because somewhere, somehow, Kim Dotcom touched USD and/or US movie studios so the US has "right" to make whatever he did their business.
