US of A - Galactic Jurisdiction?
I hope Germany tells the US to go swivel regarding the German individuals. They have form. I assume you can't be tried for the same offence twice across Germany and the US, so German justice will do nicely.
There was nothing directed at any particular country, just general cheating by VW. So the US has no reason to feel particularly affronted, but of course their courts do.
I have no hope German justice will prevail however, especially now.
