There was a time, many years ago, when British tourist's cars were occasionally stolen in various european countries, recovered by the local police, and when the tourist arrived home, stolen again, recovered again by the British police with the tyres off, and body panels and trim opened up. Sometimes the panels had been cut open with professional metal shears.
So far as I remember, the perps were never caught, and no-one knew what had been smuggled in.
There isn't much under the sun that is new.

There is some partisan argument above about Shapelle's guilt. As I understand it, she was found guilty of bringing drugs into Indonesia.
How can you argue with that? The stuff was in her bag when she arrived. She took drugs into Indonesia.
The more enlightened legal systems around would debate knowledge and intent and justice.
There is also the point that drug dealers are on a par with serial killers, totally unconcerned with other people's lives. "Some unlucky cow got twenty years, her bad luck, but I lost my dope!"

My instinct is: I shouldn't think she knew about it, or she would have been more careful.
