Nothing.......... thank goodness!!
As recently as two hundred years ago people in 'civilised' countries were thrown into filthy, stinking jails for all sorts of crimes (and even crimes they did not commit), and allowed to rot there. It didn't reduce the crime rate. We have thankfully moved past that, but some countries (like Indonesia) have not. Would you have us go back to those dark days?
What would you consider to be a long enough punishment for someone caught with a bag of dope? It wasn't heroin or cocaine, and she wasn't trying to peddle it. You have assumed guilt, but even if she did do it, I think the length of time she has served is enough. She has been severely punished for what she supposedly did; nothing can be achieved by keeping her there any longer.
Where is your compassion Tink? Do you have any?
We can't dictate to other countries, and we haven't. However, we can try and show them how to be more humane. After all, learning to treat human life with dignity and respect is one of the things that has raised our civilisation to the level we enjoy today.
I agree we need to be tougher on drug pushers, but it's a big leap from a slap on the wrist or a suspended sentence (which is what a lot of offenders get here for being found with dope) to twenty years in a filthy, disease-ridden hole that you wouldn't expect your dog to sleep in. There is also a big difference between proof beyond reasonable doubt and circumstantial evidence, which is all the Bali court had.
