No.
The Death Penalty is a final solution that solves nothing.
It causes ongoing damage and suffering to the families far longer than the public's recall of the "deterrent effect" of such "justice".
In the case of Chan and Sukuruman ....
Will it stop the flow of drugs through Indonesia?
Will it stop the flow of drugs into Australia?
Would it have been imposed if the original trial judge had been paid off?
Has it consistently been imposed in Indonesia for similar crimes?
Would they have been charged if they'd paid off the local police (or police chief) at the time?
Is it fair and reasonable to impose such a penalty after they spent 10 years on death row?
Is it fair and reasonable to impose such a penalty when they demonstrated rehabilitation?
Is it fair and reasonable to impose such a penalty when they were providing such leadership and charitable services to others?
In general terms...
Is the verdict reached by a Court always the correct one?
Do trial witnesses, including police, always tell the truth, the whole truth and nothing but the truth?
Has everyone that has been executed (in Australia, in Indonesia, and elsewhere), been guility of the offence?
... Too many miscarriages of justice over the years
... Too many successful appeals where convictions are overturned
The Death Penalty is not a deterrent, it is not an appropriate punishment, in any supposedly democratic country in an enlightened 21st century!!!
