You misunderstand the purposes of our criminal laws and our criminal courts. For individual justice (the fair recompense of individuals harmed by the actions of others) there are the civil courts.
The criminal courts are there for the protection of society as a whole. Yes, the victim has a role in the process and often a voice in the proceedings. But the purpose of the criminal courts is to balance the rights of all and render a decision based on the evidence that is within the parameters set by law, that is not arbitrary and that offers reasonable odds that those convicted will not re-offend. Some will, but in the case of serious crime, most won't. The ones that do re-offend can be designated as dangerous offenders & thus are locked away indefinitely.
Let's assume you are right, for argument's sake, that the purpose of the criminal courts is what you say:
1) to balance the rights of all,
2) to render a decision based on evidence ... offers reasonable odds that those convicted will not re-offend.
On point 1: I agree, that it balances the rights of all.
On point 2: I agree again, that it renders a decision based on evidence, etc.
But both points are predicated on what? They are predicated on the set of laws as set forth for which the criminal courts are directed to interpret and apply, that is all. If I accept the laws, then I have to accept the courts, and thus I have to agree on your points. The problem is, your points are immaterial because I wasn't arguing about the courts, I was in disagreement with the principle behind the laws themselves.
We need to throw out our current laws and replace them with a set of laws that codifies Justice correctly: it correctly balances the rights of the victim against the convicted by redressing and restoring the victim as much as possible, thus redressing and restoring society. The current set of laws applies rights to victim and the convicted as if they were equal; although the individual becomes convicted, his fundamental rights remain equal to the victim because his punishment is minimized in order not to impinge too greatly on his rights - while turning a blind eye to the vast destruction of rights to the victim by the offender and by the courts that refuse to redress them.
As I stated before, the problem with our system today is that it focuses on punishment and forgets about justice, and this is because we hold individual rights above all, even if the individual has committed a capital crime.
Did Clifford Olsen re-offend? Has Paul Bernardo? The system is working as it was intended and designed to do. Protect society.
If real Justice were in place, neither would have the chance to reoffend, forever.
The current system works if you only look at whether or not the criminal has a chance to reoffend, and you turn a blind eye to the injustice to the taxpayer who affords his lifelong imprisonment, and you turn a blind eye to the suffering of the victims and their families for which there was no effort at any redress. Simply imprisoning an offender is not the only factor in protecting society. To protect society, the victim must also be compensated or redressed or restored, and it is in the redress of the dignity of the victim and their families as human beings that the termination of these types of offenders is the only option.
