LS- In Queensland, an aircraft is a vehicle, for the purposes of the Qld. Crimes Act, it is on state where state police could have taken action, particularly as it seems Barry did not meet the medical standard for a car licence.
Does anyone know how 'wide' (for want of better) the QPS investigation is allowed to be ??. I am reliably informed that the NSW Police (for example) run an independent investigation which delves into a wide range of topics. The reasoning is to provide answers to a range of questions and to eliminate things such as suicide, murder, criminal activity etc. etc. before a matter is placed before the Coroner.
I wonder if the QPS (will) have looked into the reasons why BH was allowed to continue flying ?. There are well documented cases of guys being stopped dead in their tracks at the stroke of a pen, for much less. Perhaps this is outside of their remit; but it's a puzzle, to be sure.
