Steered from R&N, here, by David. Very late into the discussion so apologies if I am off track a bit.
Media reports where I reside suggest that the latest furore is about the judgement made that the pilot was guilty of "unlawfull killing". It is that element that the pilot sought appeal against and,it seems, won.
Again, apologies if my take of local reporting is off kelter but if I got it right, it moves the discussion into much deeper, specific, legal argument.
