Looks like another case of"collateral damage" in the war on drugs.
Indonesia is reported to have 2 million heroin addicts so it seems the war is not being won.
Under the justice system in Australia and many other countries Schappele would have been tried before a jury and probably been aquitted since the case could not be proven beyond a reasonable doubt.
In Indonesia the defence evidence was rejected as hearsay but the word of customs agents who claimed Schappelle confessed ownership (hearsay) was believed. All evidence which pointed to her innocence was called "subjective" and was disregarded.
Schappelle may well be an innocent victim in the "war on drugs".
Baggage tampering is not that improbable. However if it is accepted as a defence then we open up a whole can of worms.
This is why we cannot expect pressure on Indonesia from the Australian government.
