what about.... no prison at all?
To all you who are proposing an "island-prison" idea I can only say - you are crazy deluded violent hypocrite people. Violence only breeds violence. You can't change a person by sending him in a place where he will be beaten, raped and maybe killed.
It's ironic, that you see a violent nature of state and then propose SAME violent solution for other social problems.
So prison is not even an option. Who will pay for it? You? Your children? Hahaha funny.
Dude, with the pay per view thing it would probably turn a profit. People who like to initiate violence should want to live with people who like to initiate violence, don't you want them to be happy?
The only thing I want to add is, people exiled to the island can have a paid for sterilization. (financed from the PPV fund)
Any children born there get amnisty and raised in foster homes. (also financed from the PPV)
Please note: All this assumes a free society on the outside.
If the present governments of the world up and decided to make a government free island full of "law breakers" I would probably break a law just to go there.
