I don't agree with the death penalty
It doesn't act as a deterrent
It costs more than prison
It's too easy a punishment for the criminal - they should spend years having to consider what they have done and trying to make amends where possible
However, some of our prisons are far too easy and they do cost a fortune
I think that:
Every prisoner should have to work and the majority of the pay they get should go towards prison costs and charities which support victims of crime
If they have savings, some of that should go towards their prison costs (if single/no dependents, I would not want to take from their families if in hardship)
All prisoners should donate blood to pay back something to society
White collar criminals who are not physically dangerous should not be in prison. They should be working, but sentenced to paying a percentage of their salary towards either the company/person they stole from or a crime victim charity
If you die in hospital whilst a prisoner, you donate your organs automatically, again - to give something back
I know some people might not agree - that this is taking away their rights for them to have no choice; but they lost their right to that choice when they committed a serious crime (which their victims had no choice about)
The above might be more of a deterrent too...
