Meanwhile whilst it is fair that perpetrators should be able to be brought to account, it's surely so much hot air if the country accused aren't going to accept any reached verdict ? Nor penalty ?
I think this has the hallmarks of pleasing the citizens whilst causing big diplomatic issues which may not be something that has no affect. Particularly in that part of the world.
