Uh... for the same reason why they arrested an AMERICAN on the same charges. Who says that they had to arrest them in the UK and Australia, respectively?

These guys were probably in Afghanistan stirring up shit with their homies and got captured by US troops there. If they were apprehended in either of the two home countries, it would be those authorities dealing with them.

I'm referring to the fact that nobody outside of the U.S. would consider going out and "dealing" with the family of any accused. Even if it was considered, it's a lot of work to track people down.
