Thanks to Ray Cooper, we know that drugs were being moved interstate in unsuspecting passengers' baggage.
This was confirmed by Sir John Wheeler.
We know these drug shipments can, on rare occasions, get missed at pick-up and continue onward to an overseas destination, in this case Bali - happened to Steve & Dee in 1997.
We know the value of the marijuana in Australia - $32,000 - far more than Schapelle could have afforded, having worked for most of the year in her mother's Fish & Chip shop just to pay for her airfare.
We know the value of the marijuana in Bali - $4,400, so this rules out Schapelle acting as a drug 'mule' for someone else, since no one else would be sending marijuana to Bali to be sold for a fraction of its original value.
This explains why there has never been a case, before or since, of a commercial quantity of marijuana being intercepted at Denpasar Airport, coming off a flight from Australia. It simply doesn't go there!
Schapelle was a non-drug user, did not like marijuana, did not even like being around people who were using marijuana. Blood and urine tests confirmed that she was drug free when arrested. Despite nearly 6 years in Kerobokan Prison, where every kind of illicit drug is readily available, Schapelle has never once used them, even though many of her fellow inmates have.
Schapelle went to Bali to have a two week break from looking after her dying father, and to help her sister celebrate a birthday. Having been there before, she was well aware of the penalties for drug smuggling in Indonesia. She had no means to acquire the drugs, no desire to acquire them, considering her extreme dislike for marijuana, and absolutely no reason to take them there, where they would be worth far less.
So, this all seems very simple to me. Schapelle was, and remains, the innocent victim of a bungled interstate drug delivery.
What is less simple, is why so many influential people in Australia, (3 Prime Ministers, 2 Foreign Ministers, 2 Queensland Premiers, 2 AFP and 1 Queensland Police Commissioners, and 2 Qantas CEO's), have chosen to abandon Schapelle Corby to her fate - 20 years in a squalid third world prison, suffering serious mental illness and potentially suicidal, for a crime that she clearly did not commit. The obvious answer is: for political and commercial expediency. Schapelle was, and is, classed as a ‘nobody,’ not a member of the establishment, and therefore expendable.
Prime Minister Gillard did recently raise Schapelle's plight with the Indonesian President, and out of this discussion came renewed calls for a Prisoner Transfer Agreement. Great! If Schapelle happens to survive long enough to see a PTA finalised, which is doubtful, she will then be able to spend a few years in an Australian prison, once again, for a crime she did not commit. Thanks Julia!
